After using miui12, many friends found that the brightness of the screen cannot be adjusted, which caused trouble to many friends. If you want to solve this problem, remember to hurry up and find out more about it.
The brightness of the video cannot be adjusted in half screen. This is a problem with the desktop itself, because the first version of MIUI12 version 20.4.23 does not have this problem. After updating to version 20.4.30, the desktop version number has indeed changed.
Currently, this problem still exists even if the latest internal beta desktop is upgraded, but we can enter "Super Power Saving" and exit again, in order to restart the desktop process.
This will temporarily allow it to adjust the brightness back, or directly use the drop-down bar to adjust the brightness!
Open the "Application Center" and update the "System Desktop" to solve the problem
