Why does manual brightness adjustment not work after turning off Auto brightness on the Redmi Pad 2 4G?

Thank you for your support of Xiaomi products.
Please refer to the following explanation:
  1. The Redmi Pad 2 4G uses a virtual light-sensing mechanism instead of a physical ambient light sensor. This design helps balance performance and cost while still providing essential screen brightness functions;
  2. When Auto brightness is turned off, the system can not immediately apply manual brightness changes in real time. In some cases, the screen brightness will only update after the screen is turned off and turned on again;
  3. This is part of the expected behavior for the tablet and does not affect overall device performance. You can continue to use the device confidently without concerns about hardware issues.
