The fourth One UI 4.0 beta firmware based on Android 12 got rolled out for the Galaxy S21 series earlier today. The new beta build (firmware version ZUK1) is now available in every country that participates in the beta program, and of course, we took the latest release out for a spin in a new hands-on video at SamMobile TV.
To save you the suspense, the fourth One UI 4.0 beta update barely brings any visible additions over the previous build. Visually, the most noticeable change in beta 4 is the removal of the stretch effect when overscrolling menus. Many people liked how this effect looked, but for whatever reason, Samsung removed it and hasn't put any other effects in its place. At least not yet.
Aside from visual changes, the latest beta does seem to be fairly solid in terms of stability and bug fixes. It addresses various issues, from random crashes to the UI and certain Samsung apps misbehaving in certain scenarios.
You can refer to our hands-on video below if you want to see the old scrolling effect alongside the new, non-existent effect in One UI 4.0 beta 4. And if you already are a beta tester, you probably know the drill by now. You can now download the latest beta build via the Software update menu inside the Settings app.
