Since a week or so, the home button on my iPhone 4 is been acting very strange. From time to time, it does not react when I press it. Pressing it once, twice, 30 times in a row, nothing. So I reboot the device (have you tried turning it off and on again?) and it works again. For a while. I haven't been able to determine how long or what triggers it to stop working.
Really annoying. You pick up the phone and you want to wake it up, you press the home button. You're in an application and you want to go back to the home screen, you press the home button. You want to go the the task manager, you press the home button twice. Only it doesn't respond.
After a quick google search, I found out that I'm not the only one having this problem and that Apple knows about it too. So off I went to my local Apple dealer. They had heard about the problem but they couldn't help me, I'd have to take my phone back to the store in which I bought it and get it fixed through them. This is because Mobistar has the sole right to import iPhone in Belgium, so all repairs have to go through them as well. (or something along those lines)
But god knows how long that's going to take.... (and the great experience I've had with Mobistar in the past isn't really helping)
But since the problem doesn't occur 100% of the time and since some sources online state that reinstalling the iPhone's OS might help, I'm going to try that first.
I'll keep you posted.
