If the ambient light sensing doesn’t work after quickly double-pressing the power button to launch camera, please refer to the following details:
1. When the camera APP is running in the background, double-pressing the power button to quickly launch it will lead to a situation where the camera process takes priority and becomes actively occupied;
2. This can interfere with other system functions, such as auto brightness adjustment, which relies on ambient light sensing at the moment of screen activation. As a result, the screen brightness will not update properly in response to current lighting conditions;
3. To avoid this issue, it is recommended that you clear the camera APP from the background or manually adjust the screen brightness as needed.
