When the touchscreen malfunctions, try the following simple solutions. Please note that if the problem persists, there may be hardware damage, and it is recommended to contact a professional technician for repair.
1. Restart the device: Hold down the power button until the shutdown interface appears, then select the restart option. This method can resolve some issues caused by temporary software glitches.
2. Clean the screen: Use a soft, lint-free cloth to carefully clean the screen, removing any dirt, water stains, or particles that may affect touch sensitivity.
3. Check the screen protector: If the device has a protective film or case, ensure these accessories are intact and not interfering with touch functionality. If necessary, temporarily remove the protective film to test if touch functionality has been restored.
4. Battery Status Check: If the device's battery is swollen or malfunctioning, it may be pressing against the touch panel and causing it to malfunction. It is recommended to check the battery condition and replace any faulty batteries promptly.
5. System and Software Updates: Keep the device's operating system and applications up to date, as some touch issues may be resolved through software updates.
6. Safe Mode Test: Boot into safe mode to rule out interference from third-party applications. If touch functionality works normally in safe mode, the issue may be caused by a specific application. Try uninstalling recently installed software.
7. Reset the device: If the above methods are ineffective, consider restoring the device to its factory settings. Note that this operation will erase all user data. Be sure to back up important data before proceeding and strictly follow the manufacturer's provided instructions.
If the issue persists after completing all the above steps, there may be hardware damage. In this case, seek professional repair services for inspection and repair.
