So today unfortunately, my phone fell on the floor at school (I'm a teacher). It was on my table/desk. I don't know if a kid bumped it or not. Anyway, the corner is cracked. It's in a case, but there's not much of a lip, and I think it just fell right. After peeling away a little of the screen protector, I don't think the phone screen itself is cracked. Very thankful I got that Whitestone Dome screen protector put on last night. I don't think the Samsung one would have protected it. I immediately ordered the double pack (shoulda done that in the first place), and noticed that Amazon had an installation video on the order page. It may have been there before and I didn't notice it. Maybe the directions with the screen protector said this, but I didn't see it, and none of the other videos I'd watched had shown this step, but the video on Amazon tells you to put your finger on the fingerprint sensor for one minute after the first curing step. Then do the final curing after that. I think the video is by Whitestone, btw. Anyway, I wonder if that step would've made a difference in how well the FPS would work. Unfortunately, I'll be able to find out, lol. I would've preferred not cracking my $50 screen protector.
