S4 displays "Gamma" at bottom of lock screen?

[AC Question]

Hi, new to android and this S4 so just finding my way around.

Can anyone tell me why the lock screen of my new work S4 has the word "Gamma" displayed at the bottom of the lock screen? (just above "Emergency Call").


It doesn't appear to do anything but I can't make it go away.

If I set the unlock to just swipe and touch it I can drag it around the screen, but that's all.

Any help appreciated

Cheers
