We've all seen the JRE video where he cracked the back of an iPhone 15 Pro, and the most common explanation in the face of other videos where people failed to do the same is that he's "really strong", but then I saw this video which claims to explain why it happened, but it seems counterintuitive to me. At the end of the short clip, you can see that the back glass appears to actually be quite flexible -- they bend it a good amount (to show it's alleged flimsiness) and it doesn't break.
Presumably no amount of pressing on the back of the phone would lead to it bending that much, so how does that glass actually break?
Side note, a few people trying this (which seems dumb to try) have noted the phone makes a cracking sound before the glass actually breaks. I wonder what that could be? My friend who has an iPhone 15 Pro has a clicking sound if they press on the back glass.
