The default. It rotates around.
The first one is a drawing of women kissing, because I love lesbianism and art. The one on my homescreen is my old room.
I took a hike up Mission Peak (Fremont, CA, US) some number of years ago and had to stop 3/4 the way up as it was too muddy, but I got a good shot of the bay and have been using it on my phone since. It also has this weird feature where the lighting on it also makes it look bright but cloudy to dark and stormy depending on screen brightness.
I don’t have one of those things at the moment, but there is the other thing, which I currently use alongside an ipad, which would show those of us who go to rehearsal at a post-rehearsal event.
