I'm almost positive that my iPad Air's magnets on the right bezel are free floating. When I fold over the smart cover to cover the screen, I hear and feel clicking of something internal moving. Is this potentially damaging? This ipad replaced the first one I got that had dead pixels, and while the sound is slightly concerning, it does have one nice benefit: the magnets are much stronger when the cover is folded around the back and hold the cover firmly in place. On the first ipad, the magnets BARELY held it on the back. Apart from when opening/closing the cover, there is no rattling or movement that I can detect. Should I take this back?
