Cannot slide to open. Touchscreen not working proper
After charging my iPad when it turns on the touch screen doesn't work properly. You cannot slide to open. A black outline appears around the slide to unlock and you must keep tapping inside the outline before it moves on. His happens for everything you try to touch. I have turned power off and back on, have held the wake and power buttons down for the apple logo to pop back up, but it still does not slide properly. Help??!
