What if Huawei's mobile phone software has been reversed in black and white?

If your phone screen turns gray, you can do it 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 to make the screen grayed out. 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:

Go to Settings > Healthy Use of Mobile Phone > Sleep Time/Stop Time, and turn off the screen graying switch.

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

If "e-book mode" is not found, your mobile phone does not support this function. Please check other scenarios.

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

Warm reminder: This operation mainly restores network settings, screen lock password, desktop layout, etc. If the mobile phone supports fingerprints or faces, the fingerprint and face information will also be recovered, and other types of data or files will not be deleted. Find devices, users and accounts, device manager, application settings, etc. Will not be restored.

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 the customer service center for testing and processing.
