The third One UI 4.0 beta update was released for the Galaxy S21 series in South Korea a week ago, but Samsung is no longer accepting beta testers. That's a good sign, too, because it hints that Samsung is now getting ready to release the first polished build to the public.
The Android 12-based One UI 4.0 beta program was open to anyone who uses a Galaxy S21 in one of the participant countries. The sign-up process required the Samsung Members app, and countless Galaxy S21 owners joined the beta program to get a sneak preview of Android 12 and help steer One UI 4.0 in the right direction.
After three One UI 4.0 beta builds and a recent hotfix, Samsung closed the beta program to new participants. A Samsung Community manager confirmed today that the company is no longer accepting beta firmware recruits for One UI 4.0 on the Galaxy S21, which indicates that the beta program is nearing its end.
The beta program could soon reopen for Galaxy Z Flip 3 and Galaxy Z Fold 3 owners, but as far as the Galaxy S21 series is concerned, it looks like it might receive the first stable build soon. How soon? We can never be too sure, but Samsung hinted at a launch before the end of the year — possibly ahead of December.
