Samsung is progressing really well with One UI 8, its next major OS designed for the Galaxy smartphones, foldables, and tablets; this is perhaps due to adopting Google’s Trunk Stable development model for timely release.
With the Galaxy S24 series alongside the Galaxy Z Fold 6 and Flip 6 units, they are already testing the One UI 8 beta version in a few selective countries; meanwhile, it appears like the Galaxy S23 series is supposed to be getting the ongoing One UI 8 beta program anytime soon.
Well, Samsung has already announced the details regarding the plans of the expansion of the latest Android 16-based One UI 8 beta program to even more eligible Galaxy models, while also clarifying that the Galaxy S25 series will begin getting the official (stable) One UI 8 version beginning in September 2025; it’s natural that other eligible models will be testing the beta build at that time.
Meanwhile, it looks like the One UI 8 beta program for the Galaxy S23 series could perhaps begin very soon, as, according to the tipster, the first-ever One UI 8 beta build has been spotted on the test servers, which is identified with the version number S918BXXU8ZYH7.

And now that the Galaxy S23 models have just made their exclusive appearance on the test servers, therefore hinting that Samsung’s ongoing One UI 8 beta program for the 2023 flagships can start anytime soon.
Currently, Samsung has expanded the latest Android 16-based One UI 8 beta program for the Galaxy S24 series and the Galaxy Z Fold 6 and Flip 6. At the same time, the Galaxy S25 owners just received the fifth One UI 8 beta version, and all in all, it looks like Samsung’s latest One UI 8 will enter its stability stage next month, at least if the progress goes like this.
