The shutter sound effect plays when you snap a photo with the built-in camera on your LG Optimus smartphone. If you find this bothersome, however, you can disable this sound on most models in the Optimus family. Find the shutter sound settings -- as well as a number of other features, like resolution, flash and timer options -- in your Camera app's advanced settings.

Step 1

Navigate to your Home screen, and then launch the "Camera" app.

Step 2

Tap the gear icon to launch the Advanced Settings menu once your camera's viewfinder appears.

Step 3

Tap "Shutter Sound," and then disable the sound effect.
