The Samsung Galaxy S25 series, launched in January, came pre-installed with One UI 7, based on Android 15. While the rollout of this OS to other devices in Samsung’s portfolio is still underway, the company is already preparing for its next major update. According to recent reports, Samsung has started testing One UI 8, which is expected to be based on Android 16. A tipster uncovered an internal test build of the new OS on the company’s servers, indicating that Samsung has begun development of the next-generation software.
This information was shared by @tarunvats33 on X (formerly Twitter), where the tipster revealed that the internal build of One UI 8 had been listed as a “newfound test firmware.” The build, identified by version numbers S938BXXU1BYC1/S938BOXM1BYC1/S938BXXU1BYC1, marks the beginning of testing for Samsung’s future OS update. This early start to development suggests that the company is working ahead of schedule, beginning the process about two months earlier than usual. However, it’s important to note that this doesn’t mean beta testing has started yet, and the public rollout is expected to follow Samsung’s usual timeline later in the year.
One UI 8 will likely be based on Android 16, which is expected to be officially released in June 2025. An official from Samsung recently confirmed that Android 16 would be launched in that timeframe, with a possible move to the Android Open Source Project (AOSP) by June 3, 2025. Once this happens, developers will be able to start creating custom versions of the OS for different devices, leading up to its public release. The launch of One UI 8 will bring new features and improvements to the Galaxy S25 series and other Samsung devices, further enhancing the user experience.
The early development of One UI 8 demonstrates Samsung’s commitment to staying ahead of the curve in the competitive smartphone market. With Android 16’s official release in the pipeline, users can expect significant updates that will enhance both performance and functionality. Samsung is likely to continue refining One UI 8 throughout the year, ensuring a smooth and polished experience when it eventually reaches devices worldwide.
