What should I do if the touch screen of my mobile phone fails?
The ambient temperature is too low.
If the ambient temperature of your mobile phone is too low, the touch screen may fail, which is affected by the physical characteristics of the screen device itself. It is recommended that you put your mobile phone at an ambient temperature of 0℃-35℃ as much as possible.
Forced restart
Please press and hold the "power on" key 10s or more, and try to restart the phone forcibly. If the problem still cannot be solved, it is recommended that you bring the relevant purchase voucher to Huawei customer service center for testing. Warm reminder: In the EMUI 1 1.0 version, the way to forcibly restart the mobile phone is to hold down the volume down key and the power on key at the same time for more than 10 second. If the data has not been backed up before, there is a risk of data loss during the test.
