Why did Huawei's mobile phone become a black and white screen?

If the mobile phone is pasted with a toughened film or a third-party protective film, it will lead to some deviation in the screen color of the mobile phone. It is recommended that you observe the color of the screen without sticking the film. At the same time, individual tripartite themes will also lead to abnormal screen color. Please change it to the official theme and check it again. If there is still a problem with the color of your mobile phone, please troubleshoot it according to the following scenario.

Scene 1:

Open the simulated color space. Close method: Enter the settings, search the simulated color space, and select Close. (If the Analog Color Space option is not found, you have not turned on this switch. Please skip this troubleshooting. )

When the e-book mode is turned on, the screen will turn black and white. Closing method: enter the settings, search and click the e-book mode, and close the e-book mode.

Scenario 2:

The system application background shows black: the dark mode function is turned on. Closing method: go to Settings > Display and Brightness >; Dark mode, turn off the dark mode switch.

The background of the three-party application shows black: the dark mode of the application itself is turned on. I suggest you go to Application > My > Settings > Turn off dark mode and slide the switch.

Scenario 3:

The open drain mask enables the color inversion function. Turn off method: Go to Settings, search, and click Color Inversion to turn off this switch.
