Here are a few potential solutions that may help:
1. Restart the device: Sometimes, a simple restart can fix touch screen issues. Press and hold the power button to turn off the device, and then turn it back on.

2. Clear the cache partition: Clearing the cache partition can fix touch screen issues caused by software bugs. To do this, turn off the device, press and hold the power, volume up, and home buttons at the same time, and then release the buttons when the device vibrates. Use the volume buttons to navigate to the "wipe cache partition" option, and then select it with the power button.

3. Check for software updates: Make sure your device is running the latest software. Go to "Settings" > "Software update" to check for updates.

4. Calibrate the touch screen: Go to "Settings" > "Advanced features" > "Sensors" > "Touch screen calibration" to calibrate the touch screen.

5. Factory reset: If none of the above solutions work, a factory reset may fix the problem. However, this will erase all data on the device.

6. Check the third party apps you have installed, some of them could cause touch screen problem, try to uninstall the apps you suspect.

7. If the problem persist, it's likely that the touch screen is damaged and you need to replace it with a new one.

It's worth noting that if the issue is hardware-related, replacing the touch screen or the device may be the best solution.
