Ok so it looks probably closest to this, kind of like a black hole but all white/bluish white with the Apple logo in the center. It’s happened like 4-5 times over the last month or two and, while it’s nice to look at, it’s very confusing lol
Lasts probably two seconds, not associated with any notifications that I receive, and it’s not like the “ring closed” animation. I’ve turned screenshotting on in hopes I can catch it but no such luck thus far.
Edit: Series 8, 10.1.1
Does it do it when you hold your phone against your watch? If so it’s probably the new NameDrop feature.
