Samsung starts testing Android 14-based One UI 6 for Galaxy devices

Samsung Galaxy S23 Ultra Review AM AH 20

Samsung seems to have begun testing Android 14 for Galaxy devices. Twitter user @tarunvats33 recently spotted the first One UI 6 test build for the Galaxy S23 series on the company’s servers. The Korean firm is also testing the new One UI version for the Galaxy Z Fold 4 and Galaxy Z Flip 4. One UI 6 is Samsung’s custom software based on Android 14.

Samsung is already testing Android 14 for Galaxy devices

Android 14 is still very much in the early stage of development. Google has only released one beta build so far, with a second beta expected anytime now. We should hear more about the next major Android update at the Google I/O annual conference later today. Meanwhile, Samsung isn’t waiting for the second Android 14 beta build to arrive. The world’s largest smartphone maker has already started testing the new Android version for its Galaxy devices, with One UI on top.

The first One UI 6 test build for the Galaxy S23 Ultra has the build number S918BXXU1BWE2. The update type confirms that it’s a One UI update. The build number also gives it away. The fourth to last character indicates whether an update is a major software release. Every Galaxy device arrives with “A” in that place. It changes to B, C, D, and so on with each major update. Here, the fourth to last character is “B”, which indicates that it’s the first major update for the Galaxy S23 Ultra. The latest Samsung flagship debuted with One UI 5.1 (current firmware version S918BXXS1AWD1).

Samsung also appears to be testing One UI 6 on the Galaxy S23+, and probably the base Galaxy S23 as well. Separately, SamMobile spotted One UI 6 test builds for the Galaxy Z Fold 4 and Galaxy Z Flip 4 as well. The build numbers for the two foldables are F936BXXU2DWE1 and F721BXXU2DWD7, respectively. “D” in the fourth to last place means One UI 6 will be the third major update for the duo. They debuted with Android 12-based One UI 4.1.1 and have since received updates to Android 13-based One UI 5.0 and One UI 5.1.


The stable One UI 6 update should arrive by October

Note that these One UI 6 builds for the Galaxy S23 series and the two foldables aren’t available to the public. Samsung is currently internally testing the new One UI version. But it beginning the test so early suggests a public beta will begin early too. These devices should get a beta program ahead of others, such as the Galaxy S22 series. We will let you know when the company shares more information. Samsung’s stable Android 14 update with One UI 6 is expected to arrive in October this year.
