Started getting a message "To access notification center swipe up from bottom"

[Android Central Question]

Galaxy S7 Android 8-There is also a solid blue circle that shows up and it moves from the bottom of the screen to the top. I have tried swiping and nothing happens. I don't know if this has anything to do with the recent universal notification test on Tuesday but it started very shortly after and have added no new apps, made no changes to settings etc.

Welcome to Android Central! It sounds like some kind of tutorial for an app, or some hidden "feature" of an app you installed. I put that in quotes, because oftentimes these features are chock full of ads. Does it go away in Safe Mode? https://support.t-mobile.com/docs/DOC-28008
