sapphire also would allow the phone to be made with titanium without having cooling problems due to having a lot better heat transfer than tempered glass, but any scratch would make it easily break too
People mistake hardness for durability, but it's just one aspect. Yes, it's hard to scratch sapphire, I can rub a chunk on the concrete and it's the concrete that will scratch.
Drop that same chunk of sapphire on the concrete and it will break or chip with ease. I've broken lab sapphire from just fat fingered fumbling it onto the floor from sitting height.
