What is this screen called (Nougat on S8+)

[AC Question]

Hi all,

I just got a Samsung s8+ and I have a S-View Flip Cover. That is the cover where it can be closed yet I can still see the screen.

What is the name of the screen that I see if I have the cover closed and press the power button? It has the time on two rows (hours above minutes), date, and some notification icons. I would like to change it.

I thought it was the AOD screen but I changed the AOD in setup and the cover screen still shows the default. As far as I can tell the AOD screen is the one where, if I have the cover open and press the power button, the AOD screen is what shows.

What am I doing wrong?

TIA,

Steven
