How to cancel the black screen background of Huawei mobile phone

1. After turning on dark mode or dark power-saving skin, the screen background will be adjusted to dark tone. I suggest you turn it off. Closing method:

Go to Settings, search and click Dark Mode. If the switch is on, turn it off.

Go to Settings > Battery > Dark Energy Saving Skin. If the switch is on, just turn it off.

2. After turning on the e-book mode, your mobile phone will become a black-and-white screen, which is more suitable for reading and text scenes. Turn off this function if you don't need it. Closing mode: enter Settings, search, click E-book mode, and close E-book mode.

3. Color inversion can change the display color of text and background on the screen. After the phone is turned on, the phone will turn into white characters on a black background. Turn off this function if you don't need it. Closing method: Go to Settings, search, and click Color Reversal. If the switch is on, turn off the switch.

If the above troubleshooting does not solve the problem, you can try to restore all the settings of your phone. If the problem still exists, please back up important data in advance (WeChat /qq and other applications need to be backed up separately), and bring the purchase voucher to Huawei customer service center for testing and processing.
