What are some must have Android apps?
Edit: I wrote this answer for “must have Android apps” but these are same apps which have changed the way I used to live my life. Each and every App has helped me in one or the other way. I hope you will also find them helpful and a bit life changing. So here is the list: 10. Psiphon For those who use WiFi with proxy settings. So Psiphon bypasses and tunnel the websites or app through a different IP Address. 9. Mirror It's a simple app to record your mobile screen. Based on the concept of CamStudio in PC where you can record your screen, Mirror offers recording of your Mobile screen. 8. NTES- National Train Enquiry System If you are from India and you want to know the running status, cancelled train (partial or fully), Live Station and other features, this App is a must have. 7. VOLT Simple but effective for those who want to learn new vocabulary. That's too obvious, then why not others? Coz here you get the “memory key” which helps you relate the words and easier to remember them. 6. Parchi It a note making app. But here’s a catch. You can view, review, edit and add right from your lockscreen without need to open the app. Isn't that amazing! I personally find this app very useful. 5. edX If you are student or a learner who wants learn something new everyday, and cannot afford to go in the prestigious institutions like MIT, Harvard University, Cambridge, IITM, etc ten it is a must have app. Enroll yourself in any course and Bazinga!! You are ready to learn from the most amazing professors. Similar to edX, we have Coursera. 4. Walnut Manage your expenses on your finger tips. Its easier then that. It shows you your monthly expenditure, ATM locations, bill remainders and many more features. Its a must have app. 3. CamScanner Everyone doesn’t own a scanner but most of us have camera. So click the pic, upload to CamScanner and voila you are done. You have the scanned copy of your documents, notes, Marksheet and upload them on your DigiLocker. 2. inshorts Till now you all must be knowing this app. The tagline is also simple “News in 60 words” and trust me it is worth having. In this “I don't have time” world, you need news to be fast and accurate so here it is. 1. DigiLocker If you have this app then you don’t need to carry your personal documents like driving license, Adhar card, voter ID card, or even your Marksheets. Keep them safe in actual locker and leave the rest to your DigiLocker. And the best part is that it is acceptable as the original ones at every governmental or non governmental institution because it is developed under Digital India initiative. That's it for the day. Thank you and Enjoy !!! Update 1: Today I came across two new apps which I found useful. Hope it would help you all. 1.Forest : Stay focused Features • A self-motivated and interesting way to help you beat phone addiction • Stay focused and get more things done • Share your forest and compete with friends • Track your history in a simple and pleasant way • Earn reward and unlock more tree species • Customize your whitelist : Leaving Forest and using apps in whitelist won’t kill your tree. 2. Swachh Bharat Toilet Locator Swachh Bharat Toilet Locator is specifically useful for Indians who're committed for Swachh Bharat. Update 2: So I am back with yet another interesting app for you all. And trust me it is worth hanving. You are bored just go through it and kaboooom !!! You are into a black hole. Enjoy the ride. 3. Curiosity It is the latest app I installed but got addicted to it. It’s exactly works like its name, generates a curiosity which inturn increases your knowledge. It covers a large field of scope from Humanity to science to faith and many more. This app deserves more snapshots but why to increase the length of my answer. Comment below if you think the list should be updated? Thank you.

What are your thoughts on Draft National Encryption Policy (INDIA)? Why are the experts worried?
Here are some of the quick facts about National Encryption Policy, presented in a timeline format. This may help you to judge if we should be worried or not.What is the national encryption policy?As stated in the proposed draft, the policy demands all the citizens to store plain-texts of encrypted information for 90 days from the date of implementation.In order to meet the demands of law and concerned department, users should be able to produce the plain-text whenever required.The responsibility of regulating algorithms and key sizes for encryption will rest with Indian government only.Encryption: meaning and historyEncryption refers to modification of the electronic data into a form that can be read by the person who knows translation of codes. Julius Caeser used this technique to shuffle letters, during the Roman Empire.Need for encryption - PurposeAs the policy states, it aims at providing the privacy of information to the citizens and the protection of business related data.Another reason behind this policy is to establish coherence, credibility and stability among various information networks and systems.However, the fact that few other parts of the policy contradict its sole primary purpose, can't be overlooked.Government to soon regulate encryption standards (22nd Sep 2015)Soon after the National Encryption Policy is put into effect, removing whatsapp and google hangout messages will be counted as illegitimate.The online businesses will be asked to keep the confidential information of users, like passwords by saving as plain text.The policy has been framed by a body working under the Department of Electronics and Information Technology (DeitY).Encryption policy: A cause of concern (Drawbacks)The range of services Indian citizens can access gets narrow as they can only use those services, whose vendors have registered in India.Deleting messages from applications like Whatsapp becomes illegal.Storage of all the data is practically not as easy as ABC.One of the major reasons for resentment of this scheme is that it violates the privacy of netizens.Scheme for execution of policy (Regulation)Soon, the formation of an administrative group to monitor the implementation of the policy, will be seen.The agency will specialize in agreement of the service providers and the government to ensure proper registration as well as evaluation of the encrypted products.The policy instructs that export of encrypted products would be carried only after the approval of the designated group.Legal dimension in information technologyIndian law system readily allows such measures to be implemented.Information technology act has been formulated, that paves way for establishment of such policies. For encryption, sec 84A and for decryption, sec 69 have been added.Moreover statements listed in IT act don't restrict themselves to this zone of coding or decoding only. They meticulously define specialised technical-terms like hashing algorithms, digital signatures etc.Draft open to suggestionsThe draft of the policy has been published on the internet in order to seek suggestions and viewpoints of individuals.The email id akrishnan@deity.gov.in is open to receive comments and suggestions by netizens till October 16.Pranesh Prakash calls the scheme as a "bad idea conceived by people who do not understand encryption."Raman Singh, the policy director, Access says this policy corrodes security.Encryption controversy: Social media and whatsapp exempted (22nd Sep 2015)As the draft of the proposed encryption policy was made public, there was a huge outrage among the netizens.The government has immediately clarified that whatsapp and other social media sites, banking services and e-commerce platforms will be exempted.These businesses are however expected to store all communication in encrypted and plain-text form; they are expected to share the security-key with government when asked.Disclaimer: The above information has been extracted from Government to regulate encryption standards.I am one of the founders of NewsBytes (NewsBytes - Daily News Digest! - Android Apps on Google Play) and thought this information could be useful to people here.

What is the strongest fictional metal or material? Why?
Unobtainium: They just don't make it like that any more.Since the first tales of gods and myths, there have been legends of devices crafted, machines made, engines imagined that have been considered the strongest, most powerful, most durable devices in creation. It is the cornerstone of many such tales.And since everyone of them has some legend where their smiths created the ultimate weapon, comparing them is basically a fool's errand. So rather than engage in random and useless comparison, let's travel through myth, legend, storied lore, four colored wonders, as well as far-flung futures and see some of these mythically-indestructible materials or devices.Legendary Mythic MetalsOrichalcum (variously spelled orichalcon, orihalcon or orichalc): a metal first appeared in Plato's version of the Atlantis myth. The name means "mountain copper" in Greek, and it, indeed, often appears the color of copper or bronze. Orihalcum's properties vary heavily from source to source: sometimes its schtick is strength, sometimes it's high value, sometimes it's magic resistance, sometimes it's room-temperature superconductivity. Sometimes it floats.Atlantis : a legendary city which was reputed to have sank beneath the waves in ancient times.Cold Iron (variously called cold steel, wrought iron, magnetic iron and so on) is the traditional bane of The Fair Folk. Precisely what constitutes cold iron varies from source to source, such as being forged without heat, forged by hand, being ferromagnetic, possessing trace amounts of iridium, literally being cold, and so on. In some legends being struck with iron had a poisonous effect on the Fey, in some, even being in the same area as cold iron could be dangerous.Adamant, any impenetrably or unyieldingly hard substance; a legendary stone of impenetrable hardness, formerly sometimes identified with the diamond.Origin of adamant: Middle English, Old French, Latin, 900 AD. before 900; Middle English < Old French adamaunt < Latin adamant-(stem of adamas) hard metal (perhaps steel), diamond < Greek,equivalent to adamant- verbal adjective of damân to tame, conquer; replacing Old Eng. athamans (< Medieval Latin) and Middle English aymont < Middle French aimant < Vulgar Latin *adimant- < LatinAdamant in the Bible(Heb. shamir), Ezek. 3:9. The Greek word adamas means diamond. This is not referred to, but corundum or some kind of hard steel. It is an emblem of firmness in resisting adversaries of the truth (Zech. 7:12), and of hard-heartedness against the truth (Jer. 17:1).Legendary Indestructible WeaponsLegends abound with indestructible weapons. Here are just a few of the more well-known magical swords.Excalibur:Having many names and sometimes confused with the Sword in the Stone, the legendary Excalibur was often referred to as a Blade of Light.Impossibly light and durable, having Excalibur and its attendant scabbard made a warrior a killing machine unable to die from his wounds.Inspiration of Medieval Language & Literature: The Song of Roland (Batlle of Roncesvalles Pass, 778)DurendalDurendal (most likely from the French "durer," "to endure") is the sword of Charlemagne's paladin Roland in the literary series known as the Matter of France.In The Song of Roland, Durendal is said to contain within its golden hilt one tooth of Saint Peter, blood of Saint Basil, hair of Saint Denis, and a piece of the raiment of the Blessed Virgin Mary, and to be the sharpest sword in all existence.Roland attempted to destroy the sword to prevent it from being captured by the attacking Saracens but Durandal proved indestructible, so he hid it beneath his body along with the oliphant, the horn used to alert Charlemagne.In the poem, Roland uses the sword to hold off a hundred-thousand-strong Muslim army long enough for Charlemagne's army to retreat into France.KusanagiKusanagi-no-Tsurugi (草薙の剣?) is a legendary Japanese sword and one of three Imperial Regalia of Japan. It was originally called Ame-no-Murakumo-no-Tsurugi (天叢雲剣?, "Sword of the Gathering Clouds of Heaven") but its name was later changed to the more popular Kusanagi-no-Tsurugi ("Grass Cutting Sword").Found in the tail of a great beast by the god Susanoo-no-Mikoto it was presented to the goddess Amaterasu to settle an old grievanceIn the reign of the Twelfth Emperor, Keikō, Ame-no-Murakumo-no-Tsurugi was given to the great warrior, Yamato Takeru as part of a pair of gifts given by his aunt, Yamato-hime the Shrine Maiden of Ise Shrine, to protect her nephew in times of peril.These gifts came in handy when Yamato Takeru was lured onto an open grassland during a hunting expedition by a tsignNowerous warlord. The lord had fiery arrows loosed to ignite the grass and trap Yamato Takeru in the field so that he would burn to death. He also killed the warrior's horse to prevent his escape.Desperately, Yamato Takeru used the Ame-no-Murakumo-no-Tsurugi to cut back the grass and remove fuel from the fire, but in doing so, he discovered that the sword enabled him to control the wind and cause it to move in the direction of his swing.Taking advantage of this magic, Yamato Takeru used his other gift, fire strikers, to enlarge the fire in the direction of the lord and his men, and he used the winds controlled by the sword to sweep the blaze toward them. In triumph, Yamato Takeru renamed the sword Kusanagi-no-Tsurugi (lit. "Grasscutter Sword") to commemorate his narrow escape and victory.Super-metals of the DC UniverseKryptonianIn the Silver Age of the DC Universe, Krypton was one of most sophisticated worlds in the DC Universe. A world so incredible that anything created there was virtually indestructible once it was under a yellow sun. (Don't think about it. The writers of the era didn't and it was fine.)Superman rocket he came to Earth in was was undamaged upon traveling across space and it delivers baby Kal-el to Earth without a scratch despite its crash landing.Martha Kent was said to have unwoven the fabrics he was wrapped in and rewoven them into his only costume. The costume was indestructible except to Kal-El's heat vision, which was how she was said to have cut the material, when necessary.These two pages are from Superboy v1 #169, October 1970.In this version of the character, baby Kal-El was so hard on his clothing due to his powers manifesting as a child, he was unable to wear anything except materials woven from those fabrics. (I am not making this up.)This explanation was made as part of a series called the Superboy Legend. This was a common thing done during the period because the comics were both numerous and often had unconnected (and sometimes conflicted) stories. This was one of the early attempts to help readers keep up.This was not an imaginary story. It was written in the canon to explain how Superman's costume came to be nigh-invulnerable. The above pencil art is by Superboy artist at the time, Bob Brown, with inks by the famed Wally Wood. Some of the illustrations here, particularly the sequence where Pa shoots and blows up the blankets, are adapted from stories published in much earlier issues of Superboy.Since his costume and cape were practically indestructible, Superman's used his invulnerable cape in a number of ways in early comics.He would use his cape to protect people near him. In this case, molten lava didn't land on Miss Lane, which I am certain she considered a good thing.Superman could use it to hold dangerous materials, toxic chemicals or to protect innocents from a rain of bullets when a broad chest wasn't quite broad enough. It was pretty handy to have around when a nuclear weapon had to be contained, too.He also used it to protect passengers from the effects of friction from his passage through the atmosphere at super-speed. He would also wrap passengers, both to protect them and to maintain the anonymity of his Fortress of Solitude, in the Arctic.Superman Airlines: It's fast. It's cheap. But the accommodations make "coach" seem absolutely spacious compared to flying "mummy-wrapped."Supermanium, named for its inventor, was introduced in World's Finest #41 (Jul-Aug 1949), a prison created to contain the menace of Brainiac.According to Superman (Volume 1) #167, Superman forged it out of the heart of a star, which implied its durability was related to its molecular density.It would also make it the heaviest prison anywhere since collapsed stellar matter would be incredibly dense and highly radioactive...Supermanium's more famous appearance was in the emergency vehicle Superman created when the threat of losing his powers from a nearby red sun supernova required he create his most inauspicious vehicle, the Supermobile. Yes, it has robotic arms with super-strength and it can replicate Superman's vision powers and has an onboard computer and television.This is the Supermobile. Don't think too much about it. You'll forget it eventually. Almost every comic reader has, at least up till now. Even Superman fans pretend it didn't happen.From the isle of ThemysciraAmazonium was the name of a metal used for the construction of Wonder Woman's Bracelets of Submission. These bracelets, created by Aphrodite were to remind them of the cruel submission the Amazons suffered under Heracles. In the classic tales of Wonder Woman, binding the bracelets together removed an Amazon's abilities.The bracelets have thus far proven indestructible and able to absorb the impact of incoming attacks, allowing Wonder Woman to not only deflect automatic weapon fire, energy blasts and other projectile weaponry (Wonder Woman Vol. 1 #52, 1952)Speaking of Wonder Woman, her golden lasso was reforged from the Girdle of Hera and reputed to be all but indestructible. While the material used for its creation is never named, its magical powers include immediate submission to the will of the wielder, the ability to force the person entangled to tell the truth and the ability to change its length to whatever Wonder Woman needs it to be.In the current era of the DC Universe, (New 52) Wonder Woman is a demigod and her bracers are still indestructible (as well as a whole lot heavier) and used to bind her godlike powers, allowing her to remove them and become more powerful and more uncontrolled as long as they are removed.New Wonder Woman is scary. Really, really scary.Modern depictions of Wonder Woman indicate her sword and shield are both god-forged weapons, made by the smith-god Hephaestus and are (by his admission, alone) indestructible. Granted, there is no way to tell for certain but all of his devices are incredible durable and in the case of Wonder Woman we have seen her use said armor and weapons against other powerful magical beings such as Ares and Hades to good effect. So we can safely assume a great degree of durability due to their magical enhancement and manufacture. Did I mention it was sharp enough to carve atoms apart?It can cut Kryptonians too. Ask Faora and Zod. I would say it’s plenty sharp if not completely indestructible.ThanagarNth Metal (also called ninth metal) is a special metal found in the DC Universe. Native to Thanagar, the home planet of Katar Hol and Shayera Thal. The material possesses a number of special abilities and can take on both mystical and technological properties depending on who's using it.Among the unusual properties of Nth metal is the ability to negate gravity, allowing a person wearing an object, such as a belt, made of Nth Metal to fly. In addition, Nth metal also protects the wearer from the elements and speeds the healing of wounds, increases their strength, and protects them from extremes in temperature.Hawkgirl's mace emitted an energy field which disrupted technology and magical energies.In its animated appearance in Justice League and Justice League Unlimited, Nth metal is transuranic iron with an atomic number of 676, possesses innate anti-magical properties, is hyper-conductive and is able to invert mesons and gravitons. Hawkgirl could us it to disrupt magical attacks and magical beings.Earth (You know what it looks like)Promethium is the name given to two metal alloys: "Depleted" and "Volatile" Promethium.Depleted promethium was invented and patented by Steve Dayton of Dayton Industries. Promethium alloyed with titanium and vanadium it forms a nearly-indestructible metal."But son, I made you out of promethium, the strongest man-made metal on Earth!" Okay, Cyborg didn't take to his condition very well in the beginning.The weapon-master, Arsenal (formerly Speedy, the archer sidekick of Green Arrow), wore protective armor which comprised depleted promethium armor. The metallic components of the Justice League member Cyborg (Victor Stone), are made from depleted promethium. Victor Stone's limbs were capable of exercising superhuman strength and durability.He got better. He's a member of the Justice League. Attitude adjustment!"Volatile" Promethium is capable of absorbing energy in proportion to its mass without loss of efficiency. Depending on the volume of the material, it can be used to generate and absorb a near-limitless amount of energy.Both metals are seemingly difficult to manufacture and thus supplies are limited. Deathstroke, the Terminator, uses volatile promethium in his weapons and has been known to charge them before his missions adding to their deadly profile.30th Century, Legion of SuperheroesWelcome to the 30th century. So clean. So sterile. No trees, no grass. No soul...Inertron is a fictional metallic substance found in the DC Comics Legion of Super-Heroes universe. It is the hardest, densest substance in the DC universe, and is often used by the Legion of Super-Heroes in the 30th century. The first mention of inertron was in Adventure Comics #336.Inertron is frequently described as indestructible and impenetrable, but this applies to beings and technologies based in human strength norms. Kryptonians and Daxamites have been show to be able to break inertron if they push themselves to the limits of their strength.However, reinforced inertron structures (like prisons) can resist even their formidable strength. Karate Kid once managed to, using his formidable super-martial arts techniques, to break a set of shackles formed from inertron.A strange fact: Inertron has been eaten by 30th century residents of Bismoll of whom Matter-Eater Lad is a known representative of the species. As you can probably tell from his name, he is able to somehow, inexplicably, and I mean never to my scientific curiosity or satisfaction consume any kind of matter, at superhuman speed, without waste products, or surplus energy output while retaining a human shape in all overall appearance.The Silver Age was an age of wonders. You wonder what they were using. You wonder how long they were high. You wonder how these books made it past an editor with a straight face. An age of wonders...A member of the Legion of Unfortunately Named Heroes, Matter-Eater Lad's signature power was eating anything between him and freedom.Matter-Eater Lad once ate inertron. The most indestructible metal in the known universe. He also ate the indestructible, miraculous Miracle Machine. This was the first time he ate something that didn't agree with him.See kids, even a lame power like matter-eating can come in handy to save the universe under the right conditions. I know this is what you're doing when you think of a superhero based on this idea. I look like this when I think about the Bismolleans.How do you imprison Bismolleans? Are they a society of perfectly well-adjusted non-criminal citizens?Do Bismolleans need toothbrushes? I mean do they even have teeth? What exactly happens from inside their gumline to their "digestive tract?"Do they use antacids, er...anti-radioactives when they have an upset "whatever passes for their super-nuclear furnace" region in their mouth?Screw that: What kind of atomic nightmare is taking place in side of Bismolleans? Are they most radioactive members of the United Federation of Planets?Why aren't we powering our star-cruisers on directed energy-Bismollean power supplies? (Besides the inhumanity and monstrous reality of such an incredibly powerful energy source running on garbage and Bismollean misery...) How do we know the UFP doesn't already run this way?Charlton Universe (now a subset of the DCU)Shazamium, Marvelium and Sivanium: highly adaptable and mutable metal capable of storing fantastic levels of magical energy. Used in numerous schemes by the nefarious Dr. Sivana.The largest supply of this strange magical metal, was held by the wizard, Shazam. First appears in Captain Marvel #100.Ancient Earth TechHumans went from primitive stone tools to space age metallurgy over a period of 200,000 years.Those periods are often broken up into the Stone Age, the Bronze Age, the Iron Age and the Industrial Age, which takes the best of all of the previous technologies.I focused on weapons because that seems to be where human innovations almost always seem to be highly focused and result oriented. (Such a sad statement...)Weapons without MetalBronze Age Swords (Introduction)Iron Age swordsMaking Damascus SteelJapanese SwordsmithingModern MetallurgyModern metallurgy has taken the knowledge of previous eras and created using new discoveries on the periodic table to create new and harder and stronger metals than ever before.Maraging steels are used in jet enginees and other technologies needing strength, durability and heat tolerance.Maraging steelsMaraging steels (a portmanteau of "martensitic" and "aging") are steels (iron alloys) that are known for possessing superior strength and toughness without losing malleability, although they cannot hold a good cutting edge. Aging refers to the extended heat-treatment process.These steels are a special class of low-carbon ultra-high-strength steels that derive their strength not from carbon, but from precipitation of intermetallic compounds. The principal alloying element is 15 to 25wt.% nickel.Secondary alloying elements are added to produce intermetallic precipitates, which include cobalt, molybdenum, and titanium.Inconel Exhaust ManifoldInconelInconel is a family of austenite nickel-chromium-based superalloys. The name is a trademark of Special Metals Corporation, a wholly owned subsidiary of Precision Castparts Corp.Inconel alloys are oxidation and corrosion resistant materials well suited for service in extreme environments subjected to pressure and heat. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack.Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. Inconel’s high temperature strength is developed by solid solution strengthening or precipitation strengthening, depending on the alloy.An extremely hard metal, this tungsten rotary burr set is used to shape softer substances (meaning anything that isn't tungsten...) Tungsten carbide burr sets get excellent ratings from the craftsman crowd.Tungsten carbideTungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms.In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry.Tungsten carbide is approximately two times stiffer than steel, with a Young's modulus of approximately 530–700 GPa, and is much denser than steel or titanium.It is comparable with corundum (α-Al2O3) in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitride and diamond powder, wheels, and compounds.TitaniumTitanium can be alloyed with iron, aluminium, vanadium, and molybdenum, among other elements, to produce strong, lightweight alloys for aerospace (jet engines, missiles, and spacecraft), military, industrial process (chemicals and petro-chemicals, desalination plants, pulp, and paper), automotive, agri-food, medical prostheses, orthopedic implants, dental and endodontic instruments and files, dental implants, sporting goods, jewelry, mobile phones, and other applications.The two most useful properties of the metal are corrosion resistance and the highest strength-to-density ratio of any metallic element. In its unalloyed condition, titanium is as strong as some steels, but less dense.There are two allotropic forms and five naturally occurring isotopes of this element, 46Ti through 50Ti, with 48Ti being the most abundant (73.8%). Although they have the same number of valence electrons and are in the same group in the periodic table, titanium and zirconium differ in many chemical and physical properties.Super Metals of the Marvel Universe (Earth-616)Marvel's canon Earth-616 is rife with imaginary metals and metallic alloys. Most of these have nothing to do with real science and everything to do with comic hyperbole.The short list includes:Proto-Adamantium: The adamantium-vibranium found uniquely within Captain America's shield (now with added Uru!) A device so unusually durable, it has only been broken a handful of times in its entire existence.In any case where it shouldn't have been broken, it was later retconned and a facsimile was being broken instead. It has only failed against magical beings who were wielding the Odin-force, an all-powerful magic, and the source of the Asgard's mystical might. The shield also failed against the Thanos when he was using the Infinity Gems.The shield's greatest strength is its nearly immutable nature and resistance to being damaged or changed. The process used to create adamantium requires the material be brought together, shaped and within a fixed amount of time before setting.The process used to create Captain America's shield was similar to the normal process of adamantium development with the inclusion of vibranium. The process was lost and therefore unable to be repeated.I accept this is the origin of Captain America's shield BUT:Thanks to a sleepy scientist and a time traveler from the future...I mean what we are to expect, some vibranium found its way into the secured locked lab when it wasn't there before?And with the mysterious addition of vibranium, we create a device which has been at the center of dozens of temporal events which changed the future.Nobody, Tony Stark, Reed Richards, or Doctor Doom have tried to figure out why they can't recreate Captain America's shield because...what? It would give Stark or Doom the perfect impenetrable armor, resistant to everything in the universe?Why wouldn't Reed Richards want to sit around for a few weekends with Cap's shield and learn how it was made so he could make everything he wants to keep COMPLETELY INVULNERABLE? Isn't that worth a weekend or two, Reed?When you can't get Proto-Adamantium (and you can't, I tried), you end up with the next most amazing thing: Adamantium.Adamantium is incredibly hard to come by, can be used to coat normal metals to enhance their durability as well. Almost impossible to make on Earth-616, process is limited to a select few corporations. Most notably found in Ultron's nigh-indestructible carapace. It can also be found coating Doctor Octopus' tentacles increasing their durability and strength.Yes, this android which is beating both Thor and Wonder Man like ugly step-children. Ultron is coated in Adamantium making his super-strength even more formidable, because he can put his back into every swing. No stress fractures on him...no strings either.Secondary Adamantium: When you can't afford real adamantium, you make, buy or steal this. Nearly as good, far more durable than normal metallic alloys, very, very expensive.Adamantium Beta: Wolverine's Skeleton and claws are made from this. Unique to Wolverine or any mutant fitted with secondary adamantium which is somehow altered by their regenerative properties (There's at least a couple - Lady Deathstrike, Sabertooth - see, I named two.) Don't think any more about it. Impenetrable metal worn down by regeneration powers... Here you go ladies, a picture of Hugh Jackman as Wolverine.Vibranium A: A metallic substance which absorbs vibrational energy, once found exclusively in the African kingdom of Wakanda. It was of extraterrestrial origins. The Wakandan stockpile was recently destroyed before Marvel's soft reboot in Secret Wars 2015.While not as durable as Adamantium, it is a very resilient alloy and can be very durable particularly when it comes to absorbing incoming kinetic energy attacks. Vibranium A makes for great body armor and can allow a properly fitted wearer to fall great distances without injury. Black Panther once wore a uniform fitted with a variety of vibranium technologies for his protection.Vibranium B: Also known as anti-metal, which destroys metallic bonds even in adamantium. Black Panther used to have claws made from it. This material was found exclusively in the Savage Land.Uh. I forgot to mention the Savage Land has dinosaurs. And mutants. And Humans running around with saber-toothed beasts. Some guy name Ka-Zar...In the Marvel Cinematic UniverseCaptain America's shield in the Marvel Cinematic Universe (Earth-199999) is NOT indestructible; far from it.Created by Howard Stark from a vibranium alloy, the MCU shield is very tough but nowhere near as durable as Captain America's shield in the comics. With sufficient force or continued bombardment, a shield composed of only vibranium can be destroyed as the vibranium destabilizes.VibraniumVibranium is not as hard or dense as Adamantium, but it is still very durable. The apparent observable vibratory rate of the molecules of the Vibranium itself does not noticeably increase when the Vibranium absorbs mechanical energy.The outside vibratory energy is stored within the bonds between the molecules making up the Vibranium. As a result, a chunk of Vibranium which had absorbed a considerable amount of vibratory energy would be exceedingly hard to demolish.If enough force were were applied to this chunk to smash it, the Vibranium would explode, releasing much of the absorbed energy in a fashion similar to a large multi-megaton bomb.Captain America's MCU shield is composed singularly from a vibranium-metallic alloy. Durable, tough, damage resistant, capable of taking a hit from even Mjolnir, but far weaker than the comic version of Cap's shield.Runner-Ups after Adamantium for durabilityCarbonadium: Carbonadium is a resilient, unstable metal that is vastly stronger than steel; think of it as a synthetic and poor man's adamantium, very durable but also radioactively toxic as well. Must have a healing factor to use this metal. Most commonly associated with Omega Red. (above)You might want to duck. Mjolnir coming through!Enchanted uru is not made or normally found on Earth and is both more resistant to damage than normal uru metal but it is not indestructible.It's durable and can be enchanted to be even more damage-resistant but its primary benefit is the ability to bind amazing enchantments to it. Thor's hammer, Mjolnir, is made of from it; hard to come by, even in Asgard, dwarves horde it.The titanic tussle between two titans who terrorize timid tenants: Hercules, Prince of Power versus the Mighty Thor.Adamantine: To be fair to Marvel's Olympians, I will also include Adamantine, the material Hercules' Golden mace is was forged from. In the Marvel Universe, adamantine is a mystical metal capable of being enchanted and having its durability enhanced through mystical/scientific forging by Hephaestus, the smith of the Olympian gods.Iron Man Armors: - composed of metallic and ceramic-enhanced alloys allowing for durability, these armors can have their strength and durability further enhanced by charging it with electrical energies and integrated force fields.Osmium: A real metal, it makes this list because Colossus, the Living Juggernaut's mutant power is to transform into a being composed of an organic or living form of this dense and resilient metal.Cosmically-Enhanced Materials in the Marvel UniverseIn the current iterations of the Marvel Universe, the nature of the most powerful materials would be similar to the nature of the technological capabilities of the species; more advanced species would likely have better metallurgical technologies.In addition to better metallurgy these species may be able to infuse materials with energy, reinforcing the material's strength, resilience and durability.Adding to this mixture, concepts such as nanotechnology, memory materials, programmable matter and other meta-material science means such species have an unknowable advantage over species without such advancements.Their armors may be self-repairing, adaptable to varying environmental conditions on their own and maybe even self-aware, able to compensate against threats without direction from its wearer.Beings who have mastered all of the universes fundamental forces, matter and energy manipulation making them with the proper scientific knowledge to create the penultimate meta-materials. These entities include the Elders of the Universe, the Stranger and the the armor of the Space gods, the Celestials.Galactus, Scourge of Worlds, was ancient when the Universe was new. He forged his current armor from materials in this universe and except for in the presence of matter manipulation entities whose powers rival his own, his armor is impenetrable.Since Galactus imbues his heralds with a segment of the Power Cosmic, they too have some ability to create nearly indestructible materials either as armor or weapons unable to be affected by beings with lesser technologies. This includes the Silver Surfer's surfboard and the ax and armor of Terrax the Tamer.Galactus created the Silver Surfer, so it's safe to say the Silver Surfer is highly resistant to damage, considering his job duties and the potential threats he faces, he needs to be. Skirting black holes, wormholes, and stars, the Surfer's metallic skin is one of the toughest surfaces imaginable.Since Galactus and the Surfer both possess matter transmutation and advanced scientific capacity they can create or alter matter to make the strongest materials in the Universe. Other cosmic beings can likely create similar near-ultimate materials.This may also include unique weapons of the local god-like beings associated with Earth, such as Odin's spear, Gungnir.In the Marvel Universe, just because a particular metal ranks well, does not mean it cannot be damaged. With sufficient force, magic, technology or knowledge, almost anything can trump anything else, hence the reason Thor and the Hulk manage to damage anyone and everyone on this list at least some of the time.RingworldRingworld is a 1970 science fiction novel by Larry Niven, set in his Known Space universe and considered a classic of science fiction literature. Niven later added four sequels and four prequels. These books tie into numerous other books set in Known Space. Ringworld won the Nebula Award in 1970, as well as both the Hugo Award and Locus Award in 1971.General Products Hull:In Larry Niven's fictional Known Space universe, General Products is a Pierson's Puppeteers company which produces various spacecraft components.The most famous (and most profitable) items produced by General Products are General Products hulls, which are advertised as being impervious to anything apart from visible light (as defined by wavelengths visible to any of the species which are customers of General Products), antimatter, and gravity.The hulls are advertised as being capable of passing through the upper atmosphere of a star without damage, although the contents may become overcooked (but see below for a solution to this problem).The company even offers a guarantee that, should anything harm you within a General Products hull as a result of a failure of these specifications, you (or your estate) will receive a very large sum of money ("tens of millions" of "stars" in the event of a death, with a "star" having value roughly equivalent to one United States dollar in the middle of the 20th century).In the history of General Products this indemnity has been claimed only once, by Gregory Pelton, whose hull failed under extremely unusual circumstances (see Flatlander).Scrith:Scrith is the milky-gray translucent, nearly frictionless material that forms the walls and floor of the Ringworld in Larry Niven’s Ringworld.It is said that Scrith was artificially produced by transmutation of matter, and is nearly impervious to most weapons. Scrith absorbs heat and radiation nearly perfectly and can block neutrinos as well as a light year worth of lead.Some amateur scientists postulated Scrith couldn't technically exist since the mathematics to create Ringworld would require Scrith to be stronger than the strong nuclear force! Impossible.This means the Ringworld cannot exist outside of an appropriately-belief suspended environment.Lord of the RingsMithril: was a precious Silvery metal, very lightweight but capable of providing extreme strength in alloys, which was mined by the Dwarves in the deep mines of Khazad-dûm. This was considered a rare gift and extremely strong metal. Highly prized it was rarely seen in hands outside of dwarves.Galvorn: was the shining black metal devised by master craftsman Eöl. It was harder than mithril and nearly impossible to smith by anyone but a master-craftsman. The technique was believed lost when Eöl died.Tilkal: was a unique metal created by the Vala Aulë in the earlier forms of the legendarium.The metal was composed of six different metals that made it extremely strong, hard, bright, and smooth. The light that shown on it and what it was exposed to caused it to vary in color. Only Aulë knew the secret of its manufacture. It was used to bind Melkor for his tsignNowery in the Silmarillion.The Culture (Iain Banks - Consider Phlebas)An artist's representation of the very durable, nearly-living starships of Iain Bank's Culture GSV.General Systems VehicleEach Systems Vehicle was a great space-faring city that represented everything the Culture was socially, technologically, etc.. They built smaller ships, such as General Contact Units, and manned them from their own populations.A General Systems Vehicle (GSV) was the largest and most capable type of Systems Vehicle, and served as the Culture's premier ambassadors. The Culture's capabilities were almost totally mirrored on a smaller scale in a GSV.These titanic vessels house vast populations, factories or defense forces -- each controlled by a trio of extremely powerful artificial intelligences called Minds.These number crunchers do all the heavy lifting while the humanoids in their charge are free to peruse whatever sort of hedonistic or altruistic lifestyle they desire.Star Wars MaterialsWith the lightsaber as the gold standard for damage-dealing in the Star Wars universe, you might be surprised to discover there were numerous metals, compounds and even genetically engineered creatures who could resist a lightsaber's gentle touch.All of these metals, compounds or alloys are resistant to the plasma temperatures of a light-saber, which makes them pretty durable. Most were very rare or expensive and thus found themselves in the hands of soldiers, bounty hunters, warriors and occasionally Jedi and Sith.Lightsaber-resistant materials (Wookiepedia - Star Wars Wiki)Amphistaff: Genetically engineered serpentine creatures that served as the primary anti-personnel weapons of the Yuuzhan Vong.Amphistaffs were one of the most durable objects known, as not even lightsabers could cut through them. When used as a heavy staff, the serpent would endure blow after blow from the Jedi weaponry and remain unfazed.The amphistaff's edge—measured in atoms—slashed through flesh with no resistance. In the blink of an eye, the amphistaff could soften and wind around the lightsaber's blade, its venomous jaws snapping and tearing at the unfortunate victim's face.Because of its organic nature, these creatures were capable of recovering from virtually any wounds. Nigh indestructible, an amphistaff could only be killed by repeated blunt trauma to or removal of the head.Cortosis ore: A very rare, brittle, fibrous material whose conductive properties caused lightsabers to temporarily short out upon contact. This effect made cortosis a useful material for anti-lightsaber melee weapons, though with repeated strikes, a lightsaber could still cut through it. Cortosis, due to its energy resistant properties, was also resistant to blaster fire.Felucian Skullblade: Felucian Skullblades were constructed from the skull and teeth of specific native creatures. These creatures grew trace amounts of Force-reactive crystals, similar to those used in the construction of lightsabers, in their bones allowing weapons constructed from them, when imbued with the Force, to block lightsabers and blaster fire.Mandalorian iron: also known by its Mando'a name of beskar, was a near-indestructible iron ore whose only known source was the Outer Rim world of Mandalore and its moon, Concordia. The Mandalorian warrior culture that inhabited Mandalore mined their planet for beskar, using it in the creation of weapons, armor, and starships, occasionally even selling the rare and valuable metal on the galactic market. A versatile metal, Mandalorian iron could be melded into multiple alloys and forged into various configurations.Mandalorian warriors in trademark armors prepare for their next battle.Neuranium: was a metallic substance used to shield from radiation, and one of the heaviest and densest metals in the galaxy. A millimeter of it could stop most scanners, and it could even temporarily block lightsaber energy. However in order to cover a space as large as a cargo hold, it would be prohibitively heavy and thus inefficient to use.Phrik: was a rare metallic compound that was one of only a few lightsaber-resistant substances known. It was used in the construction of extremely light and durable battle armor as well as melee weapons. On a more extreme scale, at one point in the Galactic Civil War, a container of phrik was able to stay intact when it was on the surface of Alderaan during its destruction. Very rare, very expensive.Songsteel: was an extraordinarily light and luminescent silver metal, used in masterwork swords and staves. The metal was reserved only for the most exquisite of weapons, and was extremely tedious to forge and shape. Songsteel was highly resistant to lightsaber strikes in a manner similar to phrik and cortosis.Ultrachrome: was a metal used as starship armor around the time of the Great Sith War. Silver and superconductive, it reflected blaster and slugthrower weaponry, was heavily resistant to lightsaber attacks, and was immune to metal-eating fungi.Vonduun crab: The vonduun crab was an organism used to shape the vonduun crab armor suits of the Yuuzhan Vong.This list is nowhere near complete..."Pardon the crudity of the model, I didn't have time to paint it or cut it to scale."If you can think of a metal, well-known or interesting artifact or nigh-indestructible technology that should be on this list, write it in the comments with some information on how to find it, what books it came from and if I know anything about it, I will add it to the list. Thanks for reading.

Which blockchain-related project has the most impressive technology?
The biggest impact on industry will have IOTA in my eyes. Impact means that you’ll see communicating devices on this plattform all over the world in every sensor…. if they manage their roadmap! Otherwise they might get caught by Cardano.Guess it’s better to distinguish by branches: For traditional banking it could be XRP, for non-traditional banking/payment it might be NEM (especially Africa as I know), Greenback will be BTC, Contracting is ETH, NEO for payment/gambling/gaming in Asia, LTC more in US/EU (?), Dash for fast transactions, …Time will show us!

Which is the best samsung smartphone under 30000?
Best Mobile PhonesOnePlus 6The OnePlus 6 is a refreshing glass-based design change for the phone series. Not only does the phone pack the latest flagship processor and up to a whopping 8GB of RAM, it still comes with a solid battery life. Most importantly, the OnePlus 6 features a much improved camera that even beats the iPhone X. OxygenOS continues to deliver a super slick performance, with its intuitive navigation gestures taking advantage of the stunning AMOLED screen’s larger real estate. The lack of microSD expansion and wireless charging may annoy some, but the OnePlus 6 delivers the best balance between performance and value.Buy from amazon affiliate link Oneplus 6 Midnight Black 6 GB GB LPDDR4X Ram 64 GB MemoryHardware and DesignBuild quality has never been an issue for OnePlus devices, and the 6 is no exception. When it comes to form factor, the jump between the 5T and the 6 is a relatively small one -- down to the near-identical width and height, the subtle curvature across the back and the rounded, tapered edges all around. OnePlus' unique alert slider is here to stay, except it's been moved to the top-right corner. The phone is comfortable to hold, and, with a gentle weight bump to 6.2 ounces (177g), it strikes a nice balance between portability and premium feel.The major difference with the OnePlus 6 is that the series has finally ditched the full metallic approach, replacing it with a glass-clad design. It comes in three flavors: a glossy Mirror Black that gives off a ceramic-like shine, a matte Midnight Black with a softer finish and an equally smooth matte Silk White, which is wrapped in a rose gold frame.OnePlus chose to mimic the special material using glass. The company managed to achieve the same elegant look, but without the brittleness, extra weight and higher production cost of actual ceramic. This obviously requires additional work: Once the glass is bent into shape, it goes through an additional five-layer coating treatment, and the result is a convincing ceramic finish that helps highlight OnePlus' signature curviness.What pleases me the most about the OnePlus 6's design is how the company is once again embracing symmetry, particularly with the central, vertical placement of the camera module on the back. It just looks a lot more premium on that gently curved surface.Perhaps it is a little ironic, then, that the OnePlus 6 is the latest smartphone to join the notch party. Over time, the notch has started to grow on me. It actually makes perfect sense, given OnePlus' return to symmetry, design-wise: it's either the notch or having to somehow blend the front camera into the chin. As someone who eventually got tired of more bizarre selfie-camera solutions, the notch approach is far more elegant and painless. But if you absolutely can't stand the notch, you can still hide it with a black bar in settings.With the additional screen space surrounding the notch, OnePlus' stunning 1080p AMOLED screen now comes in at 6.28 inches wide, with a long 19:9 aspect ratio, covering a good 84 percent of the body. It's an excellent screen -- plus there's power-saving advantages to this resolution -- but if I must nitpick, it would have been nice if it were a little brighter. That's not to say the OnePlus 6 is useless under the sun; the screen manages on most days, but I've found that it can be hard to read with the intense summer sunshine here in Hong Kong. Meanwhile, LG manages to tackle this problem by offering a 1,000-nit super bright mode on the G7 ThinQ's LCD. It's something that's simply not possible with current OLED-based displays.Software and PerformanceWhen it comes to software, you won't find any AI gimmicks, bloatware or heavy skinning on the OnePlus 6; instead, you get a clean interface with a buttery-smooth response. I've been enjoying this Android 8.1–based OxygenOS a lot: I've yet to experience any lag or crash. Of course, Qualcomm's top-tierSnapdragon 845 chipset plus the 8GB of RAM in my unit deserve some of that credit. OnePlus's engineers have apparently labored over scrolling and transitions to make them as smooth as possible -- and it shows.My favorite software feature is the new set of navigation gestures. With these, I get to fully appreciate the extra screen real estate: Gone is the navigation bar at the bottom, and instead I swipe up from the middle of the chin to go home, swipe up and hold to see recent apps, or swipe up from either the left or right side to go back. I was already used to the similarly intuitive gestures on the iPhone X, so soon after I enabled navigation gestures, I fell in love with my OnePlus 6 for the second time.Given that the 3,300mAh battery here is pretty standard, I did wonder if it would be enough to sustain the OnePlus 6's slick performance. As it turns out, I had nothing to worry about. Over the past few days, I've seen my OnePlus 6 lasting for between 13 and 18 hours on a single charge, with the former including a smooth round of PUBG Mobile, several video streams over LTE and a fair bit of camera usage. It's safe to say that on any normal day, this phone will have plenty of juice left by the time you get home. But if you do end up with a depleted battery, the bundled Dash Charger takes only about 30 minutes to pump it back up to 50 percent, then a further 80 minutes to signNow full charge.CameraOnePlus is sticking to a similar dual-camera formula, consisting of a 16-megapixel main sensor and a 20-megapixel secondary sensor for bokeh effects. This time, it's finally giving what the users have been asking for: optical image stabilization and larger pixels for the main camera, with 480fps super-slow-motion capture at 720p on the side. OnePlus says it will also be adding a new Portrait Mode to the 16-megapixel front camera later, which will rely on an AI algorithm to add stars, hearts and other decorations at a matching level of focus (or blur).Left: OnePlus 6; right: OnePlus 5T.What impressed me the most here was the vast improvement in low-light performance on the 6. When in darker conditions, the 5T switches to the secondary camera and combines pixels to boost sensitivity, but it loses a great deal of detail in the process. That's not the case with the 6: As I compared my nighttime shots side by side, I noticed that the newer model sticks to its much improved main camera, which is able to produce sharp and accurate low-light shots on its own. I even tried long exposure on the streets, and to my surprise, I was able to get many steady and stunning handheld shots. Don't get me wrong, though: I can still see some noise in certain parts of the photos, but at least they are well contained and tend not to be that obvious.Rest assured, daytime shots taken with the OnePlus 6 are also impressive. The colors pop out accurately, especially in my landscape and foliage shots. I'm further impressed by how I can see individual strands of hair in my dog's quick portrait shot. Similarly, the electronic image stabilization worked well in many of my video clips -- it's almost as if I had my phone on a gimbal, so long as I didn't move the phone around too quickly. The 5T achieves similar stabilization results, but, in both videos and photos, it misses out on some color and warmth, as well as detail in the dark areas.Left: OnePlus 6; right: iPhone X.Comparing with my far more expensive iPhone X, I'm still surprised by how the OnePlus 6 comes out with more accurate colors and clarity in most situations. In my outdoor shots, the iPhone X just about beat the OnePlus 6 in terms of sharpness, but I still prefer the latter's colors. Bring the phones back inside and you'll have OnePlus 6 as the clear winner: Its low-light shots are notably cleaner and more realistic, whereas the iPhone X has to make do with an unnatural brightness boost, while also suffering from heavy noise suppression. It seems that OnePlus has finally created a camera that's ready to challenge those from other top-tier smartphones.The competitionFor a relatively small brand, OnePlus relies heavily on the loyalty of its consumer base, so the OnePlus 6's biggest competitors are naturally its own predecessors. Many fans might not be convinced at first with that slight price hike, but the new flagship combines a fresh premium design with a much improved camera, plus up-to-date specs, making it an upgrade worth jumping on.In Asia, the OnePlus 6's direct competitor is none other than Xiaomi's Mi Mix 2S, which is priced and specced almost identically, and it targets a similar consumer base using a real ceramic design plus a screen sans notch -- it has placed the selfie camera in the chin instead. That said, given the nature of both Android systems, chances are Western consumers will lean toward OxygenOS' native Android-like look and feel. And besides, it's unclear when or if Xiaomi will be bringing its current flagship to Europe by way of Three -- let alone the US.For the rest of the world, OnePlus is all about tempting those who are seeking a top-tier flagship smartphone but don't necessarily have the budget to splash on the likes of Apple and Samsung. There's the Galaxy S9+, which packs similar core specs but with a starting price of $840 -- about $310 more than what OnePlus is asking for. As per our earlier review, the S9+ is predictably capable, and those extra hundreds of dollars ensure a handful of extra goodies, including dual-aperture camera, a more powerful 960fps super-slow-motion video capture, microSD expansion, wireless charging and IP68 rating against water and other accidents. The LG G7 ThinQ may also be a worthy contender, with a similar display execution but more versatile cameras, crazy-loud speaker, military-spec ruggedness and, again, microSD storage; we're just waiting to hear about its US launch.And last but not least, we have the iPhone X and the iPhone 8 series, but, based on my camera comparison alone, the OnePlus 6 already has a leading advantage on that end.Wrap-upAs a refinement of the already well-made OnePlus 5T, the OnePlus 6 is a big step toward the company's vision of "the perfect smartphone." Still, it depends on how one defines "perfect"; at least from a technical standpoint, the OnePlus 6 is stuck with a lower screen resolution than other flagships, and it never hurts to have a brighter screen, or wireless charging.But for me, the OnePlus 6 has hit most of the sweet spots: This is a uniquely gorgeous device with intuitive features, as well as solid battery life and a great camera. Then I remember that attractive price.It may not pack as many bells and whistles as its competitors, but it's not as if it'll be needing those: Most of us don't need AR Emoji, Animoji or AI-assisted camera filters. It's safe to say that the OnePlus 6 will most likely win over existing fans, and hopefully win the affections of other buyers along the way, too.Buy from amazon affiliate link Oneplus 6 Midnight Black 6 GB GB LPDDR4X Ram 64 GB MemorySource [1] [1] OnePlus 6 review: A big step closer to the perfect smartphoneOneplus 5t₹32,999.00Buy Now from Amazon affiliate link OnePlus 5T (Midnight Black 6GB RAM + 64GB memory)OnePlus 5T comes with 6.01-inch FHD display and it looks stunning. The colours are accurate and OnePlus has improved the sunlight legibility. OnePlus decision to stick with 1080p display is a good decision for the battery but bad for VR. It has the same design and aesthetics that of OnePlus 5 apart from the fact that the fingerprint is now located at back. The phone feels solid to hold but since the screen is now bigger it becomes difficult to signNow the top of the screen with one hand.However, the phone is protected by Gorilla Glass 5 to provide insurance to accidental drops.Performance and SoftwareOnePlus 5T runs on Android 7.1.1 Nougat and will be upgraded to Android 8.0 in December. As you know you get Oxygen OS which is very minimalistic Avatar of stock Android with forks. In my opinion, Oxygen os is the best software across any android phone. Let it be customisation or general performance. The phone is powered by a Snapdragon 835 and comes in two storage & ram variants. Regardless of which one you pick. Both variants will be equally potent. In my usage of 6 GB variant.CameraThe image quality is seriously high and details rich. OnePlus 5T has incorporated 13 MP + 20 MP camera both of them have a f/1.7 aperture for better low light photos. In daylight, photos have good Dynamic Range and colours are tad oversaturated. You also get a Manual Mode which if you use correctly can yield some exceptional results. You can record up to 4k but the 4k footage is good only in daylight. When you record it in low light the footage is jaggery and is unusable. I would recommend shooting in 1080p. There is also 60 FPS support by default. Selfie camera clicks good selfies but I'd recommend switching off the beauty mode as it makes the photos soft and unnatural. The one plus claim of better low light photos isn't quite what company claims and instead of the dual camera had they chosen one good camera like Samsung Galaxy S8 it would have been better. Also, the portrait mode is seriously poor and needed to be fixed.BatteryThe phone easily lasts one full day of usage with 5 hours of SOT on average. You do get Dash charge which is probably the best charging tech in the world.Fingerprint sensor at back is blazing fast but people used to front facing fingerprint with find it bit annoying at first. But OnePlus has given face unlock which is basically a software-driven tech unlike Face ID( by Apple ) which uses 3D mapping of your face. Nevertheless, the face unlock is fast and accurate and no you can't fool it with a photo. The alert slider is a must-have feature. ButOnePlus decision to omit IR blaster is not good The phone isn't waterproof and phones like LG G6, Nokia 8 are waterproof and splash-proof respectively.OnePlus 5T costs same has OnePlus 5 but comes with much better display and slightly better cameras. However, OnePlus could have easily launched this phone as OnePlus 5.OnePlus can increase price before people start moving to other brands. If you don't want to buy OnePlus 5T, LG G6 is perfect phone and if you bond with Nokia, Nokia 8 is a fantastic phone with the latest software. That's all from this review. I hope this helps you in making an informed decisionNokia 8 ( 64GB)Nokia + Carl Zeiss + brand = PERFECTION13 MP of color thing one cam and 13 MP OF BLACK ND WHITE OR MONO lens on second rear cam .. mono has a clear and awesome clarity than the color one .. but you get two mixed pixel pic when u clickSomething has to say is little shutter lag have to hold mobile for a second or two to complete the capturing process ..Beautiful aperture and a bit good in low-light photography tooComing to front cam .. Wow new introductory”A BOTHIE” .. but this feature already introduced by Korean giant Samsung in its Samsung S4 AND 5 BUT THAT’S not called as BOTHIE may be a one and halfThis Nokia got a better thing than that and front cam is good and average in dark places totally a good cam ( wait don’t compare with iPhone 8 plus or X )Video 4K recorded hassle.free no lag awesome original can feel what’s an Zeiss is .Processor is killer .. don’t have VULKAN but can beat it ..NOKIA is truly back!•Design:Nokia is not giving something poppy like Lumias now, they've made the device more Serious, Simple and Sensuous... Slim and luxurious body with very ergonomic curves make the device comfortable to use. Flushed camera bump and clean back is a plus. Colors match the beautiful finishing of materials.Performance:Who offers a PC grade cooling solution in a phone? welp, Nokia does... As a productive person with a gaming rig, 8 is the best choice if you're looking for a 'Gaming Phone'! I've tried most of the high graphics and power hungry games and haven't experienced a single Lag or crash, 8 manages to keep it cool even on multi-tasked gaming. Stock Android pumps all the hardware as well.BatteryOn idle, the phone used only 5% battery in 10 hrs, With gaming and heavy browsing it's lasting for around 8 hrs.Display:All that crazy performance flows through the QHD IPS with stunning color range, sharp details and extreme brightness. It kinda beats my 4k monitor...Camera. or should I say Cameras:Three 13MP Zeiss optics cameras, well the photos and videos are crazier that the craziness of those specifications. Beautiful color captures pumped by a mono sensor for insane boost in the sharpness is heart whelming. I didn't really care about the new Bothie feature, but it turns out to be very useful, in fact the first photo I took was a Bothie... See camera samples in attachments.•Built quality:NOKIA GRADE CONFIRMED!!! 6000 grade Aluminium makes the device lightweight and sturdy at same time. the shape of the body makes manages to keep the device 'unbendable'. I'd have liked metal mesh in earpiece though. Glass is beautifully merged with the body. Buttons are also metal and are very tactile. Antenna bands are kind of down throw since they take up quite a lot of surface and are at a very vulnerable place- corners. Finish makes the device feel premium AF.The rest:MIC are a plus if you like your surround system.Speaker is loud and clear.Fingerprint scanner is kind of small but is fast and precise.Type C with Fast Charge is a plus.AUX port, I don't really care since I use 4 Bluetooth devices but, is good to have.In box accessories are premium as well.Expandable storage is a win...Buy from amazon affiliate link:Nokia 8Samsung Galaxy Note 8Overall Rating: 4.7 / 5 based on 310 reviews.Highlights: Battery Capacity: 3300 mah, Primary Camera: 8 mp, Display Type: Full Hd Resolution, Os Name: Android 7 - Nougat, Ram | Memory: 6 gb, Sim: Dual SIMGrab this product at the lowest price of ₹67900.

It has a notch on the top of the bezel-less screen and features a vertically stacked dual camera module on the back. Vivo V9 is made out of a plastic shell with a metallic finish. My phone picked up scratches within days of use. That’s not a good sign, however company provides free back case. If you are someone who do not like to use back cover you will have to use this phone very carefully to avoid getting scratches on phone.Phone front is a 19:9 display with smaller bezels and it looks premium.Display Colors are extremely good and natural with HDR quality.Best for watching movies, camera and games.Display ratio is 19:9 and i have adjusted the video aspect ratio. Edge to edge display works for all youtube and video players after performing necessary settings.CameraVivo V9 has16MP and 5MP snappers at the back placed vertically, along with a single LED flash. The results were fairly impressive considering the price point of the phone. The V9 did a good job in capturing the subject outdoors.Front and rear cameras are awesome. Both works excellent in low light condition.Selfie with AI mode absolutely stunns you with the output. Eventhough it is not having front flash, it delivers good image in low lights also.In low light conditions, Vivo V9 didn’t disappoint either. When zoomed in, there’s definitely noise and that’s okay. The V9 does a fine job in blurring the background, but it should have done better and no doubt it needs improvement. In addition, there’s a 24MP front camera for taking selfie. It has also got an AI-powered beautify mode. The 24MP front snapper is decent enough for self-portraits and video calling.PerformancePowered by a Snapdragon 626 processor and 4GB RAM, the Vivo V9 is essentially a mid-range phone. It doesn't mean that performance is weak. It can handle whatever you throw at it. Vivo V9 opened demanding apps like Facebook and Twitter quickly. It also handled games with ease and without being getting hot. The Vivo V9 comes with 64GB storage, and you can also add a microSD card with up to 256GB. The AnTuTu scores were in the mid-range.Cons:-- Fingerprint needs improvement- Camera background blurr is okay however not as good as expected- Price should have been below 20k- Phone gets scratches easily.VerdictVivo V9 is purely a camera phone with internals that works well as a daily user. Built entirely for selfies and the rear camera, Vivo has also focused on its design. A new refreshed shiny/glossy back with a notch and gestures that gives a feel of an iPhone X.If photos and music is your requirement, you should buy it.Buy from amazon affiliate link Vivo V9Nokia 7 plus) Google Nexus 5X12.3MP primary camera with 1.55µm pixels/f2.0 aperture, 4K video recording, dual flash, IR laser auto focus and 5MP front facing camera5.2-inch (13.2 centimeters) FHD IPS capacitive touchscreen with 1920 x 1080 pixels resolution and 423 ppi pixel densityAndroid v6 Marshmallow operating system with 1.8GHz 64-bit Qualcomm Snapdragon 808 hexa core processor, 2GB RAM, 16GB internal memory and single nano SIM2700mAH lithium-ion battery providing talk-time of 17 hours on 3G networks and standby time of 300 hours on 3G networks1 year manufacturer warranty for device and 6 months manufacturer warranty for in-box accessories including batteries from the date of purchaseCAMERA ~ # : During the Reddit AMA this is what one of the Google Employees said about the Camera on these phones"'Both devices have the same camera ' a 12.3MP camera, with a large 1.55um pixels, which works great in all conditions ' especially low light. And both have LDAF for fast auto-focus." - Google"In Short, both 6P and 5X have Great Cameras ( Sony IMX377 Sensor ). Both take great photos in Good Lighting conditions and take better usable photos in Low Light conditions thanks to bigger 1.55um pixels. However, there is one big feature which is normally seen on Flagship Android phones missing in these phones- Optical Image Stabilization. Google says there is no need for that since the bigger pixels allow you to take low light shots in faster shutter speeds resulting in blur free images. However, that's not always the case in real world scenarios. Nexus 6P at least have Electronic Image Stabilization when recording videos while 5X doesn't even have that.# ~ PERFORMANCE ~ #Even though 5X doesn't have the top of the line processor, Snapdragon 808 is powerful enough to do most of your day to day activities. In real world scenarios you wouldn't find much difference in performance between these two phones.Quoting Ron Amadeo - Ars Technica Android Reviewer - "Spec sheet enthusiasts will whip out their spreadsheets and declare the 6P to be the superior device, but performance-wise there's little difference you would notice in day-to-day use. The 6P runs hotter than the 5X, due to both the Snapdragon 810 and the heat-dissipating metal body."Android Marshmallow - Android 6.0 is Super Cool. Even on low end Android One devices, the performance has been satisfactory. On powerful devices like these, it runs lag free and super smooth most of the time, with lovely animations. There is also Google Now on Tap feature on board, which in my opinion is the killer feature in Marshmallow. Both features always on Google Now command which works great. The Finger Print Reader is super fast and accurate on both.# ~ BATTERY ~ #Nexus 6P has a bigger battery on board comparing to 2700mAh one on Nexus 5X. However, 6P has a bigger higher pixel dense screen to power up, so the difference in battery backup between these two devices are not that big. Still 6P lasts more comparing to 5X in tests. It is disappointing that neither of these devices come with Qualcomm quick charging or fast wireless charging. However these devices support fast charging via USB Type-C.~ # Why you should Consider getting a Nexus device over any other Flagship phone? # ~The No 1 reason for me is the Software Updates. These Nexus devices are gonna get treated to the Latest Android versions for another two years. Not only that, you are gonna get critical security updates for another 3 years via OTA which means you will be running the most secure Android phone in the market. Until now, Nexus devices always shipped with average cameras, but that's not the case with these new phones, making it more attractive and value for money option for many.
