I had a blown speaker on my day 1 Incredible and called verizon to send me out a replacement. Before I sent the old one back I tried with all my might to scratch the screen just so I know what it can take. I used my car keys and scratched as hard as I could on the phones screen for a while and it didn't leave one mark. I then stepped my game up and used the sharp edge of a pair of scissors and it didn't leave one mark. I used a knife and tried super hard to leave a mark on the screen and nothing happened. Needless to say I no longer use a screen protector and still haven't had 1 scratch on the screen. It also feels nicer without a screen protector to me
