In addition, if the touch screen of your device is faulty or disordered, please refer to the following suggestions after restarting the device:

1. It is recommended that you clean the screen first, and please avoid stains such as sweat stains on your hands to eliminate external interference;

2. If your mobile phone is covered with film, I suggest you remove the film and try it. It is not excluded that it is caused by the quality problem of the film;

3. Please confirm whether it appears in the interface of individual third-party software. If so, it may be a software anomaly or compatibility problem. It is recommended that you uninstall and reinstall or replace other types of software.

4. If the above operation fails, please back up the fuselage data and try to restore the factory setting operation.

5. If the problem still cannot be solved effectively, it may be caused by the failure of the underlying driver of the system or the touch screen itself. For your normal use in the future, it is recommended that you take time to go to a nearby Lenovo authorized repair station for specific examination and treatment.
