A couple of years back with the iPhone 7, Apple started using a thinner layer of sapphire to protect the rear camera lens. When the usual suspects on YouTube started doing their scratch tests, it turned out the lens cover scratched at a level 6 Mohs rather than a level 9 as expected. Apple was forced to defend that it was actually sapphire covering the lens. Turns out that the sapphire was so thin that applying enough pressure caused small fractures in the sapphire. What looked like scratching was actually sapphire fracturing because it is a naturally brittle material and the lawyer of sapphire was so thin.
I wonder if in its quest to thin down the S4, Apple has started using a thinner sapphire screen on the S4 and we are running into the same problem we saw with the iPhone 7. Mind you, this is all pure speculation. I have absolutely no evidence to back this up.
