    You rule… thanks that was getting really annoying. Unfortunately it wouldn’t let me disable notifications, so I Killed it! F!r.. My S4 works the way I want it to, having the camera shortcut on the lock screen is about all that looked useful in this build. That’s not enticing enough for me to risk a hole new batch of bungs and infamous VZBloatware.
