Had my galaxy s4 for about a week now with AT&T... Noticed a couple of features not working or missing. One being the 'auto unlock zone' feature. Supposed to allow the phone to be unlocked automatically when ones trusted wifi.. Appears there is no setting for it. Anyone else notice this? Also, I'm guessing this is disabled for some phones but when you have a pin or password on the lock screen, you can't use widgets or shortcuts to apps. Only when you use swipe mode, that works. Others have the same problem?
