Dear users, hello!

If the mobile phone touch screen is floating, malfunctioning, etc., there are many possible situations involved. The main reasons are interference from the external environment (temperature, magnetic field, static electricity, etc.), usage (charging), system level (software conflicts, system file instability), hardware touch screen modules or motherboard abnormalities.

According to the description, due to the abnormal failure of some areas of the touch screen after the fall, it is more likely to be caused by the abnormality involving the hardware touch screen module, we recommend that you take the time to the local Lenovo after-sales service center, so that the engineer can help you detect and solve, the address you can log in to the official website to query:

1. If the touch screen of the mobile phone fails, it may be because the mobile phone cache is too stuck, you can restart the mobile phone, and it can generally be recovered.

2. In daily use, don't open too many background programs, press and hold the menu button in the middle of the phone, you can pop up the programs opened in the background, click X to close.

3. Sometimes the touch screen failure is also related to the mobile phone system, please upgrade the mobile phone system to the latest version. After upgrading to the latest version of the system, the touch screen function will be restored.

4. If none of the above methods can be solved, and you suspect that the mobile phone has a hardware failure or poor screen contact, it is recommended to go to the after-sales point of the mobile phone for inspection and repair.
