The purported iPhone 6 sapphire display panel came off even worse in an encounter with a sheet of sandpaper in a brand-new video test, ending hopes the new screen tech would be totally scratchproof.

After taking a knife and secrets to the display without any unfavorable impact, YouTuber Marques Brownlee decided to obtain serious with some rather coarse sandpaper, in his newest post.

Compared with the Gorilla Glass iPhone 5S display, the iPhone 6 arised from the fight in better shape, showing the new product is indeed harder, but by no ways invulnerable.

That led Brownlee to the conclusion the display isn’t pure sapphire, which is higher on the Mohs scale of hardness than the sandpaper utilized in the test.

Pure sapphire (a 9 from 10 on the scale) wouldn’t have been scathed by garnet sandpaper, which gets a 7 out of 10 rating.

TouchID sensor, take a bow

Interestingly, the TouchID sensing unit on the iPhone 5S was undamaged by the sandpaper test, recommending it’s undoubtedly a purer type of the sapphire material than that made use of in the reported iPhone 6 4.7-inch display.

Brownlee says a mixed-material screen makes good sense because: a) pure sapphire would be incredibly expensive and b) the material permits the screen to flex a little.
