Have you tried rebooting the tablet?

Also, you should go into the settings and try recalibrating it.

Should neither of these help. I would try starting the device in "Safe Mode" and see if the problem occurs in there. If it doesn't, then there is probably a bad app, virus, or malware on the tablet that needs to be removed.

To get into "Safe Mode" please do the following.

1. First turn off the tablet.

2. Next press and hold "Power" until you see the manufacturers logo on the screen, then release the power button.

3. "Quickly" press "Volume Down" and hold it for few seconds until you see the message "Safe mode: ON" or something similar.

4. If you wanted disable it, simply repeat the steps above, and you should see "Safe Mode: OFF" rather than on.
