Annoyed when you can't disable shutter sound in default camera and WhatsApp camera?
This flow will automatically make it silent.
Shutter camera associates with multimedia(music) volume. Sometimes with ringer or system volume.
This flow will turn the multimedia volume all the way down, only during the cameras in foreground, and restore the volume when the cameras are closed.
This flow was built on Android 4.4.2. Some adjustment might be required if the flow doesn't work in your phone.
Added to check and set both media and ring volume level. This to silent both focusing and shutter sound for default camera.
