@mummyjanny hello,if you need to mute the camera shutter sound,create a routine with Bixby Routines as follows:When open app/Camera/-then /Sounds and vibration/Sound and volume mode -silent.It works perfectly.
@mummyjanny Sorry for the misunderstanding. In this case, try a forced restart: hold down the Power button and the Volume button (-) until the device restarts. If the problem persists, reset the camera settings from the camera settings itself, please last -clear cache and data from it.
@mummyjanny: The shutter sound is enabled by default and can't be switched off in the Camera app settings, therefore please try heading to Settings > Sounds and vibration > Volume, and check your System volume slider to make sure its at a suitable level. If it's all the way to the left, and muted, then the shutter sound won't be audible.
