https://wccftech.com/one-ui-4-0-beta-brings-more-than-70-new-changes-to-the-galaxy-s21-series/ > It has only been a few hours since Samsung started rolling out the Android 12 or One UI 4.0 beta to the Galaxy S21 series, and while I still have not received it on my device, users in the U.S. have started using it, and well, they are enjoying it. Samsung has a habit of adding changes on its own, as well. This is what makes One UI one of the most definitive Android experiences you can get. > We already knew that the new update would bring out a lot of new changes, but we now have a changelog of the latest update, and it brings over 70 new changes, making this one of the biggest updates that have come out.
