I can't express enough how long I have been waiting for this update, full of excitement, as I love new android experiences (as am sure we all here do).
Is there anything particularly wrong (bugs, glitches) that makes the update unusable?
Plenty of posts on here about A12 OneUI4 - some positive, some negative. Appears it has been buggy for a fair few people, but personally I've not had any significant issues. A second update for some devices which included the Feb security patches rolled out last week. Would advise clearing the system cache after you've updated just to clear any rouge leftovers from past firmware, along with running Galaxy App booster.
I saw those posts, but I figured that they might be outdated and things got better now. I am running the Oneui4 right now, so far no problems. Thanks for those tips.
