Yeah, it's never been dropped, especially not since I was using it in bed last night and it stayed there all night. However, it looks like the white line on the right might be the backlight? I'm not sure if that's where it's supposed to be or not. I also don't know what that would have to do with the light sensor not working and the buttons flashing non-stop while the phone is on. Or why this would have happened a few times before and only when it's in a pitch black room.
I dunno, the only only damage to the case are a few scratches in the oxidation (tiny specks) from keys and the water indicator is perfect.
