I'm not 100% sure this is the cause, but I can't think of anything else. When I go to the Google search screen or any white screen, I can see a slight brown circle in the middle of my screen. The only thing I can think of, is that the battery is getting so hot, that it's burning the screen. (Something like how the battery on the white iphones would do to the backs.) But can the battery do that to a screen? I did apply a Zagg screen protector with solution, but the brown circle is to prefect for it to come from that. So what are your thoughts on this? Also, does anyone else have this problem?
