I got my S4 a few days ago, and I've been setting it up, finding my comfort zone with widgets and app icons and so forth. I note that I'm supposed to be able to launch the camera app directly from the lock screen, but the option under Setting, My Device, Lock Screen, Lock Screen Widgets for "Favorite apps or Camera" is turned off and grayed out. Is this option only available if I disable secure locking, i.e. allow anyone who picks up the phone to use any function without face recognition, PIN, pattern, or password? Or is it disabled by some other setting I haven't found?
