Messed up pixels on iPhone 4S?

This happens on my phone whenever there are images/videos on it. Even just on home and lock screens. It moves with the images, isn't stuck in place. Any suggestions on how to fix this would be greatly appreciated.

Take it to an Apple store & tell them what's going on. They'll then tell you either how to fix it, or if in severe cases to send it in to Apple & they'll either fix it or give you a new phone.
Note: Backup all data you want to keep before doing this, just in case.

  • Will my iPhone battery get messed up? I'm on a trip and I left my phone charging in the house by accident (I'm going to try to get a friend to take it off) but I was wondering how long can it stay charging until the battery goes bad? I've heard stories so I'm just wondering if they were true.
  • Why on 8/10 of my iPhone screen are half the pixels gone? On the top part of my screen my display is normal, but below it rows of pixels are not lit up. It is only this way sometimes but it is really annoying. If you know what i'm talking about please help.
  • Why is my iPhone 4s messed up? Its stuck in horizontal mode where it only shows the albums and won't go back to vertical and no it's not on screen lock I checked
  • What are dead pixels on an iPhone and what do they look like? I received a phone today and on the top of the screen there was three bright dots and even when I changed the brightness they shown. I'm wondering if its a dead pixel and if this will affect the phone…
