(Gear) Settings - Display - (Mode toggle) Light / Dark

??

Dunno.

I don't see anything in the Alarm settings (for Clock) for Dark Mode. I think I'm using a Samsung clock rather than a Google one, but I'm not sure.

If I search for Alarm, I get Do Not Disturb and half a dozen other things, but nothing immediately obviously about Dark Mode.

(One of the big annoyances I have with Samsung phones is they duplicate a bunch of the standard Google apps and use the same name, and it's hard to get rid of them, and it's tough to remember which is which sometimes.)

Lots and lots of stuff is going on all the time on these phones...

Cheers,
Scott.
