Odd but great Lock Screen Behaviour - can't get it back
My phone has spontaneously changed to this configuration on the lock screen. I would like to get back to the previous configuration of the clock at the top and the full size pattern lock. 

It is impossible to drag or otherwise change the position of the widgets or pattern lock dots on the lock screen. Once unlocked, there is no interface to adjust the lock screen widgets. 

Galaxy S4 SGH-M919, Android 4.2.2, Touchwiz. 

Does anyone know how to configure this aspect of the lock screen?
