Screen protectors aren't as necessary as they once were , but they can still be useful. Your Gorilla Glass screen can still get scratched with the sand in your pocket , and can crack if you drop your phone. The bad news is that tempered glass protectors are also fallible to the same issues, but it's far easier to replace the glass protector than your phone's screen itself. If you've had one too many scratches in the past, it's a good way to protect your phone and get that superior glass feel.
