Not long ago, Samsung officially launched a new generation of "Android machine king" Galaxy S22 series, and according to the convention, the campaign before the new machine is about to be launched is inevitable. Recently, the official revealed that the Galaxy S22 series will no longer have its own factory screen film, which for the first time is equipped with the most rugged armor aluminum (Armor Aluminum) material, and for the first time in the front and back of the fuselage have used Corning Gorilla Victus + glass, is also one of the most rugged Samsung mobile phones, if there is a screen film needs users need to buy separately.
Although it is a long-standing thing to apply a film after buying a mobile phone, it may start from Samsung's Galaxy S22 series, and the mobile phone film may disappear. In fact, the film on the mobile phone may appear much earlier than everyone thinks, because the mobile phone has been a high-tech product since its birth, and for a long time it is still a high-value commodity, so it has naturally been more cared for by consumers.
Before the advent of touch-screen models, that is, the era of functional machines with physical keyboards, in order to protect mobile phones, consumers will use a full-cover film to wrap the fuselage, and now the earthy mobile phone sticker is the "legacy" of the envelope. Even the filming of mobile phones is almost the same thing as the cover of large household appliances such as TVs and washing machines in the home.
In the era of touch screen, touch operation has also become the selling point of such mobile phones. However, the earliest touch screen mobile phone uses a resistance screen, which needs to calculate the location of the touch through pressure changes, and the characteristic is that it needs to rely on the ITO (nano indium tin metal oxide) coating with good conductivity on the surface to deliver the electrical signal to the processor, so it also leads to the resistance screen often to be equipped with a stylus to achieve precise operation.
But the problem is to achieve the screen pressed down to achieve pressure sensing, the ITP coating of the resistance screen is like the oleophobic layer known today, it is directly applied to the surface of the substrate, and directly in contact with the air, in a sense, it is a "consumable", and long-term use is also likely to be scratched. To this end, the earliest people will use PET protective film (polyester film), a commonly used printing and packaging consumables to protect the screen. As a plastic film, the main characteristic of PET film is that the material is harder, and long-term use will not be as yellow as PVC material, but the disadvantage is that hardness and rainbow pattern cannot be combined.
By 2010, as the epoch-making iPhone 4 knocked the resistance screen into the abyss, smart phones also entered the era of capacitive screens. Although the outermost layer of the capacitive screen is a glass cover, which is more durable than the resistive screen, the value of smart phones at that time was relatively high, and even to this day, the price of high-end models accounts for a relatively considerable part of per capita disposable income. Therefore, during this period, some merchants drew inspiration from the tempered glass body of the iPhone 4 and launched a glass film.
Consumer demand for mobile phone film, but also contributed to the emergence of "flyover film", when the film is undoubtedly a door "technical work", warped edges, blistering, white edges, rainbow patterns, skewing and so on, I believe that in everyone has also encountered. Although the manufacturers of mobile phone film are also keeping pace with the times, the birth of self-service film tools such as dust stickers, alcohol wipes, dry wipes, and setting frames has indeed weakened the existence of film masters, but it is clear that not everyone's hands-on ability is online.
Since the film has become the consensus of consumers, in order to please users, mobile phone manufacturers have directly used automated assembly lines to paste the film well. Although in the increasingly harsh market competition, the origin of the mobile phone with its own film is no longer available, but the result is that now in addition to Apple's iPhone, other Android camp manufacturers basically take the mobile phone with its own film as the standard. The main reason for this may be that since consumers love to apply films, and friends and businessmen are engaged in factory filming, not doing it is equivalent to weakening the market competitiveness of their own products.
Mobile phone manufacturers obviously do not know that the film will affect the display effect of the mobile phone, after all, the excellent screen quality, no matter how high the brightness, after the film cover will be discounted, and even affect the feel, but the consumer is happy to do it, and even let the film has become an inertia. Of course, it is not that there are no mobile phone manufacturers in the previous year also high-profile declarations that they will no longer give mobile phone film, but a year later, the attitude will take a 180 ° turn, announcing that they will give users free film again.
In fact, the reason why there will be mobile phone manufacturers at the new product launch to claim how good Corning Gorilla Glass is, how good the quality of the AMOLED screen is, how durable the oleophobic layer is, but in the case that the factory film has long been standard, it is undoubtedly similar to the dislocation of claiming how good your plain face is, while using a variety of beauty without hesitation. The reason for this is that in addition to meeting the needs of consumers, the screen itself is actually not scratch-resistant, which is obviously a very important reason.
Since the iPhone 4 introduced Corning Gorilla Glass to the smartphone industry, it seems to have become a "black technology" that is both resistant to drops and wear. But the actual situation is not so, otherwise why Apple pondered to apply sapphire to the screen of iPhone and iPad, and also made a "sapphire mania" that swept the entire mobile phone circle. This is because the problem of glass material is that the two core indicators of hardness and toughness are like fish and bear paws, which are difficult to get at the same time.
It is understood that tempered glass is actually a prestressed glass, in order to improve the strength of glass will usually use chemical or physical methods, the formation of compressive stress on the surface of the glass, but the increase in toughness will lead to the attenuation of surface hardness. In terms of hardness in terms of wear resistance and toughness that determines the ability to resist falls, Corning Gorilla Glass, from the fourth to sixth generation, has chosen to focus on toughness.
Although the improvement of toughness has made the fall resistance of Gorilla Glass a qualitative leap every generation, and the safety height of the fall has evolved from 1 meter to 1.6 meters, the price is that Corning itself has long admitted that the early Gorilla Glass is stronger in wear resistance. In fact, this is closely related to the fact that smart phones in the same period, especially the high-end models using Gorilla Glass, are increasingly inclined to use curved screens, and the flexibility requirements of curved screens for glass cover panels are undoubtedly far better than those of straight screens.
Corning's decision to conform to the trend of the mobile phone industry has also made the hardness performance of Gorilla Glass from the fourth to the sixth generation unsatisfactory. According to tests by YouTube blogger Jerry RigsEverything, the fourth generation of Gorilla Glass has a Mohs hardness of 5, and by the fifth generation it is only 3, while the sixth generation is 6. The Mohs hardness was first proposed by the German mineralogist Moss in 1812, using diamond, a tapered drill needle made of the hardest natural mineral, to depict the surface of the mineral and produce scratches, and the measured depth of the scratch was used to express the hardness.
But the problem is that the general glass has a Mohs hardness of 6.5, and what really causes scratches and scratches to the mobile phone screen is never the art knife or key used by manufacturers in publicity, because the Mohs hardness of steel is actually only 5.5. The real culprit here is actually silicon dioxide (SiO), the main component of sand, and this widely distributed substance in nature is invincible. So the significance of the manufacturer to the mobile phone film is here, do not look at the plastic film itself is not resistant to scratching, but also just use the scratched film to remind users that it is time to pay attention to protect the mobile phone.
As for why Samsung dared to claim that it did not need the protection of the film on the Galaxy S22 series this time, the reason is that it uses Corning's seventh-generation Gorilla Glass Victus upgraded version "Victus+". Victus' paper data is already very luxurious, and can be dropped from a height of 2 meters to maintain good condition, while the scratch resistance is increased by 4 times. After Jerry RigsEverything also tested the Samsung Galaxy Note20 Ultra with Corning Victus, the result was a noticeable scratch at a level 7 Mohs hardness.
When Victus is already hard enough, let alone the Victus+ that continues to upgrade? Of course, the film itself actually has a cost, and the cancellation of the factory film also reduces the material cost at an objective level. The logic behind this is the same as the call of the environmental protection banner under the call of Samsung also canceled the random charger. After all, they have already spent a lot of money to buy Corning's latest products, so there is no need to let its pearls be dusted.
