Unlock effect not on my settings

[AC Question]

My phone doesn't have the option to select an "unlock effect". I have it set to 'swipe' already, but nothing, anywhere on my settings does it say anything about an unock effect. The effect itself, the bubbles, were on there one minute, and then it was gone the next. Can someone please help?

Hi, what phone do you have? I'm going to presume it's an S7;

If you go to the settings section, and browse for the “Lock screen” you’ll see a list of different features you can add to the lock screen of the Galaxy S7 or Galaxy S7 Edge.
Dual Clock – shows both home and current time zones if you’re traveling
Clock Size – makes it easier to see by making it bigger or smaller
Show the Date – self explanatory, if you want the date shown, keep this checked
Camera Shortcut – allows you to instantly unlock to the camera
Owner Information – lets users add Twitter handles or other information to the lockscreen
Unlock Effect – this changes the entire look and feel of the unlock effect and animation. We prefer watercolor.
Additional Info – allows you to add or remove weather and pedometer info from lockscreen
