What is broken if it starts apps itself?
i have an iphone 3g, and it starts apps itself. it looks like someone is touching the screen. when you "hit" the phone it works for a while, and then it starts doing stuff itself again. when you press the screen hard in the upperright corner it works fine most of the time. i have already installed a new digitizer, but it still has the same problem.
do you know what is broken?
I would think the touch screen glass would be the problem. Maybe it's bent a bit, or something. Set the phone down on a sturdy surface and see if it still malfunctions. If so, try to see where it is "taping." If the "taps" are in the same spot everytime while the iPhone is still on a sturdy surface, your problem is the glass itself. Otherwise, if the "taps" are randomly placed, some other hardware is causing this. Hope this helps anyone who has this problem.
