It's a well-known fact that Apple is exploring the use of sapphire crystals beyond the camera lens and home button, but the latest leaks hint that we could be seeing the implementation of sapphire crystal displays on the next iPhone(s).
YouTuber Marques Brownlee managed to get his hands on an alleged piece of iPhone 6's front glass panel straight from the assembly line. According to Brownlee, the front glass panel is 4.7-inches and consists of a sheet of sapphire crystal.
Brownlee highlighted two main points about sapphire crystal that you need to know. First, he states that it is "an extremely high quality material" as it is as thin as a sheet of paper and crystal clear. He noticed that there is little distortion and no colour shift when looking through the front glass panel. Second, he claims that the sapphire crystal is "really durable" after conducting a series of scratch and bend tests on the panel.
He applied "some deep pressure and pressed down really hard" with a bunch of keys and a knife, but was unable to scratch or break the front glass panel. Next, Brownlee tried to bend it with his hands and came to the conclusion that he has no way of breaking the display with his own strength.
As the front glass panel is not attached to a phone or device, Brownlee said that he could not do a drop or a corner impact test to see if the sapphire crystal glass will shatter. He concluded his video by saying that "it is almost impossible to scratch the screen with any regular use". You can check out the video below.
Assuming that the front glass panel is indeed from the assembly line and it has a sheet of sapphire crystal, you no longer need to apply a screen protector on the new iPhone(s). As with all leaks and rumours, we advise readers to take this with a pinch of salt until Apple officially announces the next iPhone(s) later this year. The rumored time frame of an official launch is sometime in early September with retail availability scheduled a week and a half after.
