Several of our readers (and one of our editors...) are reporting a bug where the iPhone Home Button does not always respond to single-click or double-clicks. It might be software related as most people seem to have begun noticing this problem after installing iOS 4.1. It was hoped the bug would be fixed in iOS 4.2.1 but no such luck. Other causes that have been considered include a hardware short or dust or lint getting under the button. Ally also mentions that it may be caused by the home button not being properly centred. Possible symptoms and fixes, after the break.
Is your iPhone Home Button not working properly?
Yes, it is as bleak as it is annoying. Have you had this bug yourself? Any other fixes you've tried?
