Hi all. My son's iPad mini's screen had to be replaced last week. Then yesterday the screen turned pinkish. Thought it was a hardware problem and took it back to iFix, just to be told that it happens when you press the screen button 3 times. I was speechless. Press it 3 times more and it turns back to normal. Apparently it is for those with sight impairments. Does not do the same on my iPad 4 though. Well, let this info save you some "embarrassment" should this happen to you.
