What about Huawei's black screen?

If you use a Huawei mobile phone and the screen of the phone turns gray, you can operate the phone in the following ways:

1. If the screen is grayed out, you may have set the sleep time/stop time to use the phone healthily and turned on the switch that grays out the screen. After a limited time, the screen will turn gray and the application icon on the desktop will dim. It is recommended that you turn off this feature. Closing method:

To enter the settings "Healthy Use of Mobile Phone" sleep time/stop time, just turn off the screen graying switch.

2. If the screen turns gray, you can turn on e-book mode. When turned on, the screen of reading and text scenes will turn gray. If you don't need it, you can turn it off. Closing method: Enter Settings, search and click E-book mode to close E-book mode.

Warm reminder: If the e-book mode is not found, your mobile phone does not support this function.

3. If the above troubleshooting still can't solve your problem, you can try to restore all the settings of your mobile phone.

If the problem persists, it may be the screen itself. Please back up important data in advance (QQ, WeChat and other third-party applications need to be backed up separately), and bring the purchase voucher to Huawei Customer Service Center for testing and processing.
