Why does the light sense fail after double-tapping the Power button of the POCO C71 to start the camera quickly?

On the POCO C71, if you find that the ambient light sensing (automatic brightness adjustment) function does not work properly after double-pressing the Power button to quickly launch the camera, this is normal.
For your reference, here are more details of the issue:
1. This happens because when the Camera app is running in the background, it continues to occupy certain system resources, including those related to light sensing. As a result, the auto-brightness function will be affected and fail to adjust the screen brightness based on ambient lighting;
2. To restore normal operation of the auto-brightness feature, it is recommended to close the Camera app from the background after use. Alternatively, you can manually adjust the screen brightness if needed.
