The screen of Huawei mate8 mobile phone failed after receiving the notice.

It is recommended that you investigate according to the following conditions:

1. If there is a strong electromagnetic field in the accessories (microwave oven, induction cooker, power station, etc. ), it is recommended to move away from the strong magnetic field to see if the screen function returns to normal. Strong electromagnetic field will affect the function of touch screen.

2. If the ambient temperature is abnormal (higher than 50 or lower than -20), it is recommended to move to other places and try again. Abnormal ambient temperature will lead to abnormal screen display and touch function.

3. If the screen is wet, sweaty or dirty: Please keep the phone clean, wipe the phone screen clean and try again. Water, sweat and dirt on the screen will affect the touch response of the screen.

4. If there is a film on the screen of the mobile phone; Please confirm whether the film thickness exceeds 0.2 mm. It is recommended to use a film with a thickness not exceeding 0.2 mm. Too thick film on the screen will affect the touch sensitivity of the screen.

5. If the screen is abnormal when charging with non-standard charger and data cable, please replace the standard charger. The interference shielding ability of non-standard charger is weak, which will affect the function of mobile phone touch screen.

6. It is recommended that you upgrade your mobile phone system to the latest version.

If the above methods fail to solve your problem, please back up your important data in advance and bring the purchase invoice to Huawei customer service center for testing and processing.
