home button is sticking and sometimes needs to be pressed a few times to work, why?
the home button on my iPhone 4 is sticking and sometimes needs to be press a few times to work, why?
iPhone 4, iOS 5.1.1
Dirt/debris interferring with the button (not entirely certain that is possible). Button/sensor is becoming worn with use.
Simple failure.
Does it really matter? Just take it to Apple, if it's still under warranty they will replace it.
