Hey there
I have the One UI6 on my S23U and broadly speaking after running a wipe partition cache it is working fine.....
BUT
Many users of A Series and S22/S21 Series devices are reporting issues. Some are aesthetics like emojis, others are more serious.
If you havent got it yet, I wouldn't be too worried, you may have dodged a bullet for now. Then again, many are saying it's fine.
