Good Lock is officially a Samsung app and you get to use the latest stuff which sometimes trickles down via a new OS update.
Once you master it there is no turning back.
Lots of you tube videos on its module .
So learn it well.
Also if you are on one ui 6.1 it's even more crazy on the customisation side.
I'd highly recommend a full reset after updating to 6.1 its worth the trouble.
Backup your stuff either in smartswitch or Google One.
But don't restore apps and settings . Rest you can restore.
Set up phone as new and reinstall apps fresh as and when you need them.
