What should I do if the touch screen of my mobile phone sometimes fails?

If you use a Huawei mobile phone and the touch screen of the mobile phone is out of order, you can troubleshoot it according to the following methods:

1. 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.

2. Please press and hold the "power on" button 10s or more to restart the phone forcibly. If the problem still cannot be solved, it is recommended that you back up important data in advance (applications such as WeChat /QQ need to be backed up separately) and bring relevant purchase vouchers 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.
