iPhone 7 camera shutter sound

Was driving me crazy too. Simple fix was just turning off “Live” photo setting, when on camera mode.

Hi

To adjust the volume of the camera shutter sound:

• Use the Ringer and Alerts volume slider in Settings > Sounds & Haptics.
• The camera shutter sound can also be muted using the Ring/Silent switch - check the position of the switch.

  (In some countries, muting is disabled).

• It is normal for there to be no camera shutter sound when taking Live Photos.

  To toggle Live Photos on / off, tap the Live Photos icon above the camera viewfinder:

As advised within my previous reply, 8 months ago.

Do you have either the volume turned completely down or the mute button flipped back?
