Camera Silencer

Camera Silencer monitors Android camera availability and temporarily reduces audio output only while another app is using a camera.

It is designed for devices and camera apps where public Android audio APIs can suppress or reduce shutter sounds without root access.

Features:
• No camera permission
• No internet permission
• No accessibility service
• Optional minimal Usage Access, only to confirm that a camera app is in the foreground
• No overlay permission
• No DND policy access
• Foreground service restores audio when the camera is released
• Optional modes for silent/vibrate-following, always-on camera silencing, and manual control

Limitations:
• Effectiveness depends on the device, OS build, region configuration, and camera app implementation.
• Some camera apps may use enforced audio paths that cannot be suppressed reliably with normal app permissions.
• Without Usage Access, Camera Silencer falls back to screen-on/unlock heuristics and may not perfectly distinguish face unlock from lock-screen camera shortcuts.
• When another app keeps media audio active, such as Picture-in-Picture or background playback, Camera Silencer may leave camera sounds audible to avoid interrupting that playback.
• If suppression stops working after the camera app was opened first, force stop the camera app once and start Camera Silencer before opening the camera again.
