Screen touch failure can be caused by a variety of reasons, such as software failure, hardware damage, or external factors such as dirt and liquid ingress. Here are some workarounds:
Restart your phone: This is one of the easiest ways to fix all kinds of phone problems. Sometimes, simply restarting the device can resolve temporary software conflicts or glitches.
Check how clean the screen is: If there is dirt, grease, or liquid on the screen, it can affect touch functionality. Wipe the screen with a clean microfiber cloth to make sure it's clean and free of stains.
Remove the screen protector or case: Sometimes, a low-quality screen protector or phone case may interfere with the normal use of the touchscreen. Try removing them and see if you get better.
Check for software updates: Make sure your phone's operating system and all apps are up to date. Software updates often contain patches that fix bugs and issues in older versions.
Factory reset: If none of the above methods solve the problem, try restoring your phone to factory settings. Note that this will delete all data on your phone, so make a backup of your data first.
Inspect for physical damage: If the screen has cracks or other obvious physical damage, you may need to replace the screen. In this case, it is best to seek a professional repair service.
Contact the manufacturer or professional repair service: If the problem persists, it may be a hardware problem that needs to be checked and repaired by a professional.
Make sure to back up your important data before taking any repair measures to avoid loss.
