Volume Locker

This app helps prevent against accidental volume changes by confirming the change you made, by either tray notification or a pop up.  If you don't approve the change, the volume will be reset within a set amount of seconds.

Great for people who accidentally changes their volume, have small kids, don't want their phone to go off accidentally in meetings, or even have apps which modify the sound settings a lot.  It works with most profiling apps: Locale & Tasker ("Locale Audio Update Notifier" plugin necessary), Timeriffic, Setting Profiles, Ring Toggle, AAM, Bedside, etc.

By setting the timeout to "instant", the locked volumes will revert instantly without prompting.

The camera permission is to prevent Volume Locker from popping up due to the shutter sound on some devices.  This app doesn't take pictures, it just detects if the camera is in use.

Features: unobtrusive, auto-start, call friendly, multiple volume lock

Exclude from task killer!

Regarding the Samsung Galaxy S:  If VL doesn't work or save your settings properly, it's due to the upgrade to 2.2.1 breaking the settings permissions.  Reinstalling won't fix it, the only fix is resetting the device.  This is a Samsung issue and not related to VL.
