Default G1 touch screen problem.
Had my G1 since day one. my touch screen is way off every once in a while. And sometimes can't even select stuff on the screen. I reboot the phone and it works again until my phone hearts up from me using it. Then problem comes back. Could it be a software problem? I am hoping not hardware. Is there anyway to reset it or calibrate the screen? Or art least tell what the problem outs? Thanks
