Samsung SYNC SGH-A707

i've heard a few people unable to silent the keypad so i figured it out, since i myself like it silent. so you go to profiles and edit the one you're using. go all the way to the right to the phone sounds and scroll all the way down then adjust the keypad/phone sound volume. i dont think this affects the camera shutter sound. if this is a repost i'm sorry but i did a search and didn't find a thread about this issue.
