After years of waiting for the update, I can say One UI 4 Android 12 is sleek, they have paid attention to litte detail. I dig the smaller font, split screen is now smoother, picture in picture is now great, ram plus does the job well. The consistency of the UI is welcome from widgets with rounded corners to icons and colour pallette.
It's great that you like it already. Still waiting to have a touch on it
Which phone u have
Galaxy S10 plus
I agree with you there, it's very polished, I can't complain much even though I haven't gone through all the updates
Ya It's much more user friendly
