Here is a list of things to do if your mobile device’s touch screen is not working properly:

1. Try restarting your device and see if that resolves the issue.
2. If restarting the device doesn’t fix the issue, check if any debris or dirt is caught in the touch screen which may be causing it to malfunction.


3. If there is no visible debris on the display of the device, try updating the device firmware. This might help resolve the issue.


4. If the steps above don’t work, try connecting the device to a laptop or desktop computer via the manufacturer’s software. This could be used to execute a reset to its factory settings.


5. Finally, if none of the steps above have worked, it is likely that the touch screen needs to be repaired or replaced.
