My husband and I both have used an LG Rumor Touch for 7 months. Recently, the touch screens have stopped working properly. It reacts as if something is touching the screen when nothing is toughing it, flipping through the menus and randomly dialing numbers. I am unable to make or answer calls or texts. Is there a way to recalibrate the screen? I have tried powering down and removing the battery to reboot, but nothing is fixing the problem. Does anyone have any ideas for me? Thanks for your help!
