So I was thrilled today when my iPhone 4S came but as soon as I turned it on, I noticed that the screen did not look as it should. It's sort of hard to describe but there seem to be crisscrossing lines in the pixels and at times it almost looks like there's a little bit of ghosting going on? When I turn the phone on, the Apple logo itself looks mostly clear, but the black background around it has faint white lines running horizontally and vertically from the Apple logo. It's very noticeable when I look at pictures in my camera roll and it's almost like have a phone with a lower resolution screen. I loved my iPhone 4's screen because of how clear everything was. Has anyone else experienced this problem and do you think Apple will exchange the device?
