I have a Samsung sam4 sps2000 till. On occasion the touch screen does not respond, normally if I restart it it works fine. When it decided to stop responding today, I restarted it but even after this the touch screen will not respond. It displays everything fine and if I press the screen with a couple of fingers it beeps, but the screen does not advance beyond the initial selection. Does anyone know why this would happen?
Any help would be greatly appreciated.
Thanks in Advance,
