You will also hear a shutter sound when you take a picture, you will hear the click sound when you lock your phone, and you will also hear typing sounds when you tap keys on the virtual keyboard.

This switch will mute incoming audio alerts and the phone will only vibrate when you get a call, a text, or any other type of alert. IPhones have a physical switch for turning sound off.
