I always keep my system volume turned all the way down. I don't know why anyone would want their phone to make obnoxious sounds when turning off. When do most people turn their phones off? Church, movies, meetings, basically anytime you want it to be QUIET. Anyway, I digress. Something keeps turning up my system volume. Often when my phone shuts down due to low battery I hear the stupid shutdown sound. I think it may also have happened a few times when powering the phone off manually. I am rooted and I know I could rename the files, but I am getting tired of working around the bugs on this thing and having to keep track of all the files I rename. I try to keep it as "stock" as possible. Any ideas on what might be turning my system volume up?
