It's kind of hard to search for this problem on the forums since there are a wide variety of issues going on with my iPhone. One of the symptoms is that when I push the volume up or down buttons, it automatically locks my phone. Sometimes it seems like the down volume button is stuck down since it would not increase the volume when I push up and there would be the volume indicator stuck on my screen. Another symptom is when I tilt my phone in random positions, it gets my phone in/out of sleep. The weirdest part is, it happens at random times. One minute it could be working just fine, then the volume would suddenly go down and stay down even if I push the volume increase button. Other times, I would push the sleep/wake button and it would then bring up the power down screen. I've tried soft and hard resets, removing applications, and full restore but the problem still persists. I haven't done anything strenuous with my iPhone other than walk around with it in my pocket. Any one else experienced this problem? Any solutions to it? Thanks in advance!
