So my dad has an iPad Air which as is always almost the case is just out of warranty. The home button has sunken down slightly on the bottom and its lost its "click" the button still works but I don't know how long for. I have tried cleaning down the sides of it with contact cleaner and a cue tip a couple of times but has not helped. I was wondering if there was dust/dirt stuck somewhere. Now I know removing the front will likely result in me shattering it, does anyone have any other suggestions or know how much Apple would charge to fix?
