Android - How do I disable the 'click' sound on the camera app?
You'll need root to delete the sound file, but this should be it:
Repercussions? It won't play the sound anymore? :)
Alternatively, you could download another camera app that does not produce a camera sound.
If you have "Tasker" installed, then
When you exit the camera app, the system volume is restored to its original state.
When you're in the camera, just use the normal volume to turn sound all the way down. This worked for me on stock Nexus One running Froyo.
