Samsung is currently working on the stable One UI 3.0 update for the Galaxy S20 series, among other things. The company has already released several new beta updates over the past couple of weeks. And now another beta version is being rolled out for the Galaxy S20 smartphones. All previous beta updates were released along with respective changelogs in the Samsung Members app, containing a list of fixes included. The new update has a general changelog without any detailed information, which probably means there aren't many issues left to fix. The stable One UI 3.0 update is expected to be released before the end of the year.
Owners of other Galaxy flagships aren't so fortunate. Samsung has postponed the One UI 3.0 beta program for the Galaxy S10, the Galaxy Note 10, the Galaxy Z Fold 2, and the Galaxy Z Flip due to issues found in the initial beta version for the Galaxy Note 10 and the Galaxy Note 10+. They may have to wait longer for the stable One UI 3.0 update.
The owners of the Galaxy S20, the Galaxy S20+, or the Galaxy S20 Ultra participating in beta testing can check for the latest update in the Settings menu(in the Software Update section). The update is already available in the UK and Germany. It should also soon reach other counties such as Poland and India.
