Earlier today, I removed my verizon screen protector from my X. At some point later in the day, I noticed what seems to be a very faint but noticeable square grid. It is most visible when I am using an app that has a white/light colored background (ex: Google.com in the browser). I can also see it when the display is asleep, but under sunlight or any other bright light. It's hard to say, but the grid also seems to be slightly more noticeable when the brightness is turned all the way up. Has anyone else experienced something similar? Could it possibly be a problem with the screen, or is it normal? (this is my first touch screen phone, so I am pretty unfamiliar with how they actually work.) Thanks for any insight!
