Why will my tablet not unlock?

[AC Question]

I have a 7" RCA tablet model #RCT6272W23. And everytime I wake it, the touch screen seems to not be working. It will not let me unlock it.

Welcome to Android Central! Did this suddenly happen? Any recent falls or trauma? I'd guess that it's a hardware failure, possibly the digitizer. Unfortunately, not that surprising with a budget device--sorry!
