Hi, I have a iPad 4 and I think there is something wrong with it's screen. Sometimes, When I go from one page to another (in the home screen), in the gaps between apps, I can see a shade of my apps, it's not easy to see, but it is there. Its like the image got stuck in the screen of the iPad. I tested it, I took a screenshot of the background and it is not there (I move the picture (in the Photos app) but the icon "shades" are like stuck in the screen, not just in the wallpaper. I will upload a photo as soon as it happens again. This thing, normally stays in the screen for a minute, than it disappears.
