My 4S is starting to have issues with the home button, it does work but often takes a couple of presses for it to register or a harder press for that matter. I have blown it out with compressed air and this does for a while but it soon goes back to being unresponsive. Same with a reboot, it fixes it temporarily. Maybe its just me but this problems only started with iOS 6. Has anyone else had these issues or do you have a solution I haven't tried?
