*Please note that these steps will cover updating some setting(s) in anticipation (of) a screen locking or freezing up. These steps cannot help you if the tablet is currently frozen.
1. Navigate to Settings on the MESA tablet and go into Keypad
2. Choose a key that you don't use often and select it (I chose the Diamond key for our example) You'll want to remap this to Touchscreen Enable/Disable
3. You are all set to go now. If you see the touch screen freeze press this button to disable the touchscreen and once more to reenable it. We've found a lot of success with restoring functionality using this method.
*Final Note: if you are unsure if your touchscreen is currently disabled or enabled please look at the top right corner of your display.
If you see this symbol with the X through it, the touchscreen is disabled.
If you see this symbol of the finger pointing down, the touchscreen is enabled.
