"possesed samsung 10.1 tablet"에 답변It called ghost touching. It sounds like you received a faulty screen. Check into the return policy and get a new one.
"Seperating the touch glass from the LCD screen?"에 답변You don't have the proper equipment to readhear a new glass to the LCD. You probably also just ordered a piece of glass which doesn't have the digitizer attached to it. You're going to have to order the entire display assembly to repair your device.
