Why is my lock screen getting a popup message?

lock screen popup message

Bought my S5 a few months ago and all was good until I suddenly started getting the following message pop up every five to ten minutes in a small black rectangular box at the bottom of the screen.
'Now your phone will run in screen lock mode for x minutes longer'
where x is any number between 1 and 15. This happens any time whether or not I have screen lock enabled. I've tried all the usual remedies of rebooting and taking the battery out. All in all very annoying and adds to the nuisance of the messages about securing the waterproof case.
Any ideas how to fix this would be much appreciated.

New phone + problem = trip to carrier for fix or replace. It's their problem (the price includes a replacement warranty), so why try to figure out such an esoteric problem? (And it may be common enough that they can push a few buttons to make it stop.)

Gravity screen also does this in some situations. Disappears after 2-3 seconds.
