Why is my iPhone 4S's home button not responding from home screen? My home button seems to be working okay to move out of apps etc, and double tapping brings up the expected menu, but on the home page, a single tap no longer swaps to the search interface, and when modifying app positions, clicking home no longer stops the apps 'shaking' - is there any way to rectify this?
These features should definitely work with the home button on your 4S. You should contact Apple to get a solution, which may include repairing or replacing the phone. If you are near an Apple retail store, set up a genius bar reservation. If not, call Apple for support.
