If manual brightness adjustment doesn’t work after enabling Auto brightness on the REDMI Pad 2, please refer to the following details:
1. The REDMI Pad 2 uses a virtual light-sensing system, which means it does not have a physical ambient light sensor;
2. As a result, the screen brightness will only adjust after the display is turned off and then turned back on;
3. Even when Auto brightness is enabled, the brightness will not change in real time during active use. This is a normal phenomenon. Please feel free to use it.
