You should put your volume/media sound to zero for the shutter sound turn off.
Same question here. I tried going to the settings, unfortunately, there is no option to turn it off. Tried also to put my phone to the silent mode, it still has the shutter sound!
Whoever knows, please let me know. Thanks
Put your phone in silent mode or check camera settings for options to turn it off.

Hope that helps! :)
