I have two Samsung tablets I use as Roon remotes. In “auto-rotate” mode (always on), Roon normally behaves like other apps; to go from portrait to landscape (or vice-versa) you simply change the way you hold the device. Normal, right?
My 2017 Tab A does this as it’s supposed to. My 2021 Tab A7 lite also did until a few days ago, but now it’s stuck in portrait.
I tried uninstalling/reinstalling the app; didn’t help.
Samsung just rolled out something called One UI. My 2021 tablet updated to it without asking me. My 2017 tablet is probably not getting updates anymore; maybe that’s why it still displays both ways?
BTW, all the other apps that normally go into landscape still do.
