Hi, I am having some intermittent issues with the home button on my iPad mini retina purchased six months ago with applecare. I sometimes have to press the home button 2-3 times before the iPad does something. It doesnt happen all the time but often enough to be irritating. My wife's iPhone 4 did something similar but I thought they changed the design. Is there a way to fix this by cleaning it? I don't want to start messing with it incase I void my applecare warranty. I've had some unpleasant experiences with Applecare warranty issues such as Apple Genius not wanting to fix/replace unit after iPhone battery not holding charge way under warranty period.
