Samsung may be testing One UI 6.0 on a small number of flagship phones one day before Google’s official announcement of Android 14. Samsung is beta testing a major upgrade to One UI, and the consensus is that it will be called One UI 6.0.
Early this morning, @tarunvats33 on Twitter discovered the first One UI 6 beta version on Samsung’s servers. This Galaxy S23 Ultra S918BXXU1BWE2 firmware is a development build intended only for internal use.
Samsung’s newest foldable phones are also participating in One UI 6.0 trials.
We discovered that Samsung is internally testing One UI 6.0 on the Galaxy Z Fold 4 and the Galaxy Z Flip 4, in addition to the Galaxy S23 series. Firmware version F936BXXU2DWE1 is associated with the Galaxy Z Fold 4, whereas firmware version F721BXXU2DWD7 is associated with the Galaxy Z Flip 4.
The Galaxy S23 series and the foldable flagship phones of 2022 should be among the first to participate in the Android 14 beta testing program later this year, and they may also be among the first to get the stable One UI 6.0 upgrade.
If you’re unfamiliar with Samsung’s software and Galaxy devices, you should know that One UI 6.0 is built on top of Android 14. The Android 14 version, which will be fully unveiled by Google tomorrow at its I/O conference, will likely serve as inspiration for some upcoming changes in Samsung’s proprietary software.
The fourth to final digit of the firmware versions S918BXXU1BWE2, F936BXXU2DWE1, and F721BXXU2DWD7 suggests that they are linked to One UI 6.0. The letter A (present on the most recent public firmware) is changed to the letter B in the Galaxy S23 beta software. Similarly, the Galaxy Z foldable phones’ internal test software has upgraded from version C (public firmware) to version D (test firmware).
A new major One UI update is indicated by a change in the fourth-to-last digit, as stated in our comprehensive Samsung firmware guide. There is a remote possibility that the test build is based on One UI 5.1.1 rather than One UI 6.0; nevertheless, given that the official release of Android 14 is expected to occur soon, we are more likely to believe the latter.
