I’ve been using one on both my Pro and PM. I never have used one in the past, ever since the 3G. I’ve never had a scratched screen until the PM. It’s very small, around 1/16” at almost the bottom edge of the phone. No idea how it got there. I just noticed it one day. I baby the phones. Designated phone pocket and nothing else goes in with it. I also never have the phone face down when on a counter, desk etc. Even so, I’ve been debating lately on taking it off.
Do you notice a quality difference with and without the screen protector that you use?
