I have never once thought that. The fact I have always wrapped my smartphones in an S view style leather case means I could give less than one shit about what the back of my phone has been made of. I watched knuckleheads freeballing their phones, dropping them, cracking the screens, and noped the fuck out of that noise before I even owned my first smart phone. Been doing the leather envelope style case ever since. Knock on wood, never cracked a screen, not tryin to win any beauty contests, just keep my thousand dollar pocket mini computer up and runnin.
