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.
