Why does the automatic brightness adjustment not work on the Redmi Pad SE 8.7?

The automatic adjustment mode can be adjusted in the following two ways when the ambient light changes:
1. When the ambient brightness changes, you can press the Power button to turn off the screen, and the interval between turning on and off is at least 3 seconds, which can realize automatic adjustment;
2. When the ambient brightness changes, the manual switch automatically adjusts the brightness setting.
Automatic brightness adjustment helps maintain optimal screen visibility without causing eye strain. In low-light conditions, reducing brightness can prevent glare, while increasing brightness in bright environments ensures the screen is easily readable.
Note:
When the ambient brightness remains constant, the device's hardware limitations prevent automatic brightness adjustment.
