Although I do not have scientific proof, I have come to the conclusion that tempered glass is nothing but a scratch protection and just marketing gimmick. If your phone screen is to be broken from drop, it will be with or without tempered glass. Tempered glass is nothing but a feeling, a feeling that your phone will be protected from drop.
On the other hand when you use tempered glass it reduced the pixel density and resolution of your phone. Also the touch screen will not be as responsive as the original glass.
So I have stop using tempered glass and instead, I get myself a good phone cover to protect my phone from shocks.
(This is just an opinion and nothing against the community who make or sells tempered glass :D )
