I'm in the same boat as you. I got the tab s10 ultra last year and think it's a tad big. I'm hoping that one of the fan editions will be a "plus" size. Maybe if you could hold out a bit, wait for them to come out.
If you click the pencil icon, you can edit the way quick panel looks. You can add, remove, and even rearrange those icons. I think by default though that there will always be 8. You can also change the order of the panels by sliding them up or down.
[emoji848] I didn't notice any difference until you just mentioned it. It does look a little more legible, but maybe my eyes are deceiving me too. Maybe slightly thicker font?
Still seems to be working for me. Unless my app is different.
Edit: well, I guess it was because I still had the app open. Closed all apps and now I get the same message.
