According to foreign media reports, apple recently installed a new glass called “ceramic shield” on its new iPhone 12, which is said to be the hardest glass ever used on a smartphone. Every year Apple makes a similar statement about its glass, but this time it may be different because it’s not ordinary glass. Although it looks and feels like ordinary glass, the ceramic shield that covers the screen, as the name suggests, is a combination of glass and ceramics – harder than most metals. < / P > < p > to find out how hard the new material is, CNET conducted some scratch and drop tests on two new iPhone 12 models. This new type of glass has proved to be very durable. < / P > < p > it is understood that this ceramic shield only covers the screen of the iPhone 12. The back uses the same glass as last year’s iPhone 11. Apple said last year’s iPhone 11 was the strongest in the industry. Both types of glass are made by Corning. < / P > < p > besides the glass, another factor that affects the performance of this mobile phone when it falls may be its design. The glass of the iPhone 12 is flush with the metal frame, rather than bent like the previous model, which exposes more glass. Apple says design options alone can make the front and rear fuselages twice as durable as the old models. < / P > < p > all four models of the iPhone 12 (iPhone 12 mini, iPhone 12, iPhone 12 pro and iPhone 12 max) use the same ceramic screen and back glass. The only difference in materials is the frame. Both pro’s have stainless steel frames, while the mini and 12 are aluminum frames. The performance of the frame may vary from material to material, but glass should provide the same type of protection. In the test of foreign media CNET, they used the blue and green regular iPhone 12. < / P > < p > in the first test, the reporter put the iPhone 12 in a small cosmetic bag, which contained some common things that damaged the phone: a bunch of keys, a half dozen quarters and a metal pen. The reporter shook the bag vigorously for about 30 seconds to simulate what would happen after a few weeks of playing in a wallet or pocket before checking it. < / P > < p > next, the reporter wants to see how the screen supports when it touches a hard surface such as a marble table, kitchen counter top or bathroom floor. The reporter swiped the iPhone 12 back and forth on a tile 10 times, first with the screen and then with the back of the phone. < / P > < p > as a result, there are fragments of tiles on the screen, but it is difficult to find any obvious glass damage after wiping it clean. Testing the back of the phone is tricky. The raised camera module does not allow the mobile phone to be laid flat, so the reporter slid the back at a certain angle. This did not damage the glass, but caused some of the metal paint on the bottom camera frame to fall off. Then the reporter extended the camera module to the edge of the tile. After carefully examining the back, the reporter finally saw two tiny scratches, one on the Silver Apple logo, the other under the blue glass. They’re all thinner than a wisp of thin hair, about a quarter of an inch. < / P > < p > after two excellent scratch tests, the reporter decided to take another extreme test on the iPhone 12: sanding with 80 grit sandpaper. This may be equivalent to sliding a cell phone across a driveway or sidewalk in the real world. < / P > < p > the reporter rubbed the phone back and forth on sandpaper 10 times and applied slight pressure. This time, both sides of the phone were scratched. The screen is most damaged. Several of the damaged parts are very deep. The reporter said that his fingernails can be touched, but his mobile phone can still be used. The damage on the back of the phone is much less, because the raised camera module provides protection, but there are still visible scratches on the center and lower edge. The metal on the lens frame continued to fall off, but there was no scratch on the lens itself. < / P > < p > friction can damage the phone glass, and when the phone falls, it is more likely to be damaged. So CNET used another brand-new iPhone 12 to conduct a drop test on the sidewalk. < / P > < p > the most common drop is when the mobile phone is put into or taken out of the pocket. Although it is harmless to drop a mobile phone from a high hip height, it may shatter the screen if it falls on the street or sidewalk. < / P > < p > when the iPhone 12 falls from hip height, the top will land first, then the bottom. After that, it will pop up again in the air and lie flat on the sidewalk, with one side of the screen facing down as expected. < / P > < p > the top of the iPhone 12 seems heavy: it lands almost as it did before, first at the top, then at the bottom, and finally it falls on the sidewalk. The main difference of this fall is that the sound of landing is louder than before. Sure enough, when it was turned over, the lower part of the mobile phone was broken. The edge of the phone feels a little rough, but there is no debris on the back. Despite the cracks, it still feels smooth. < / P > < p > in this test, the most obvious dent appeared on the top, but after wiping, the reporter found that it was only metal residue on the mobile phone frame, but the glass was still intact. < / P > < p > as the screen was still strong, the reporter decided to climb higher and use a ladder to reach nine feet. What needs to be explained here is that unless you happen to slide your mobile phone down from the balcony on the second floor, it’s an unrealistic fall, but foreign media reporters want to see how far we can slide it. < / P > < p > at 9 feet, controlling landing becomes more difficult. When reporters tried to get it flat on the screen, the iPhone 12 had its own idea and landed on the ground six feet high in almost exactly the same way. The top right corner of the screen lands first, then bounces back from the left, landing with one side of the screen facing up. < / P > < p > the reporter repeated the process twice, hoping that it would land facing the ground at a certain moment, but the weight of the camera made it difficult for it to land at that angle, especially at that height. Maybe the only way to control it is to climb to the roof or rent a scissors lift, but journalists are not prepared to do so. < p > < p > CNET said that because their tests were unscientific, they could not guarantee that the screen of the iPhone 12 was stronger than any other phone on the market, but they could say for sure that the iPhone 12 was absolutely excellent in terms of hardness, even if it fell on tiles and sidewalks. < / P > < p > Apple said in a statement providing CNET that “iPhone 12 and iPhone 12 Pro represent the biggest leap in iPhone durability The iPhone 12 has passed rigorous reality testing, and its design is durable, but not indestructible. If someone is worried that their iPhone will be damaged if it falls to the ground, we recommend using a beautiful protective cover to protect it. ” Global Tech
