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.
