Description

A possibility the multi-sensor capability of the smartphone is that alarms on some sensors could trigger an otherwise-undesirable capability that fixes the light-level problem: activating the flashlight to get a clear capture of the otherwise pitch-black environment.

Research direction
Investigate Android SensorManager for light and motion sensors (e.g., TYPE LIGHT, TYPE ACCELEROMETER). Look into CameraManager.setTorchMode to control flashlight. Review existing sensor handling in the app's codebase, such as in MainActivity or any sensor service classes. The issue lacks specifics on which sensors to use and the logic for triggering, so clarify with maintainers or propose a design.
