I am onto my second ipad mini retina. The first had dust under the screen. The second does not show traits of image retention (I tried test) but the icons in my home row can be seen through the keyboard when I go to search. Like I said, it does not it and any other times with any other keyboard. Even the similar sark keyboard in the ebay app. I can take a screen grab of it so it makes me think it is a software issue. It does it in landscape and portrait and 100% of the time regardless of how long I have been on he home screen. Thoughts anyone? I have a replacement to on the way but may keep this one if it can be solved.
