This thread I've posted may be of interest to you UK & Ireland Note9 folks.
How you getting on with ONE UI PIE9 ? Are you going to stick to it ? Or downgrade back to Oero 8.1 ?
I also quite like it so far. Especially the new features like tap to always on, a toggle for reducing animations and the new gesture navigation. I think the icons and overall look seems a bit unpolished to me. But overall i will stick to it for now.
Getting used to the new gesture navigation, as in no navigation bar/buttons. So far found just one app, Samsung Pay, that I can't install into the Samsung my folders (not optimised it says). But generally all seems ok to me. I'm using Nova so it all looks the same to me.
