What should I do if the screen of my mobile phone darkens?

If the screen of the mobile phone is very dark, it is recommended that

Check the power supply

Check whether the battery is low.

Power saving mode

Check whether power saving mode or super power saving mode is turned on.

Light sensing function

Maybe the light sensing function of the mobile phone is turned on. It is recommended to open the Settings-Display-Brightness-Cancel the automatic box and adjust the brightness manually (some machines do not support manual brightness adjustment).

Night mode

See if all interfaces are dimmed. Some applications support night mode. If only the screen of a software interface darkens, it is recommended to check whether the software is set to night mode.

Third-party energy saving software

Check whether third-party power-saving software is installed.

Restore factory settings

If the above operation still fails, it is recommended to back up the important data in the mobile phone and try to restore the machine to the factory settings.

After-sales service center

If the problem still exists, please take the machine, purchase invoice and warranty card to the local after-sales service center for inspection.
