As of May 28, 2025, Samsung has officially commenced the rollout of the One UI 8 beta in South Korea, specifically for the Galaxy S25 series. This exciting news comes alongside reports indicating that the beta, based on Android 16, has also started to become available in the United States for unlocked Galaxy S25 models and T-Mobile users. Additionally, the beta is confirmed to be rolling out in key markets such as the UK and Germany.
The inaugural One UI 8 Beta for the Galaxy S25 series carries the version number S938NKSU3ZYER and is approximately 3GB in size. According to Samsung’s changelog, users can only download beta updates over Wi-Fi, so it’s essential to ensure you have adequate free storage and a stable internet connection before proceeding with the download. For further details on the One UI 8 beta rollout, you can read more in our dedicated article.
Initially announced on May 27, 2025, Samsung’s One UI 8 beta based on Android 16 has been teased through official program pages and promotional banners on the company’s community forums and Members app across several countries. As Samsung gears up for this beta release, many users are left with pressing questions regarding eligibility and rollout plans.
Fortunately, drawing from past experiences with One UI beta releases, we can provide insights into which Galaxy devices are likely to receive the One UI 8 beta update and the expected timeline for availability.
Samsung typically restricts the initial rollout of the One UI 8 beta to its flagship devices, and this time is no different. Based on the company's historical patterns, the following devices from the Galaxy S25 series are expected to be the first recipients of the beta update:
Galaxy S25 Galaxy S25 Plus Galaxy S25 UltraThe Galaxy S25 trio is almost guaranteed to lead the charge for the One UI 8 beta, following the precedent set during the previous One UI 7 beta launch. Notably, tipster Tarun Vats identified the first One UI 8 beta build “S938BXXU3ZYEA” for the Galaxy S25 series on Samsung’s servers earlier this month, which has since been updated to the current build number “S938BXXU3ZYER” as of the announcement date.
While the Galaxy S25 Edge is part of the S25 family, it may not receive the beta update concurrently with the other models. If the Edge variant does join the One UI 8 beta program, it is likely to experience a delay due to Samsung's staggered software development processes. Furthermore, a Galaxy S25 FE model is anticipated later this year, which is expected to ship with One UI 8 pre-installed, thus making it less relevant to the beta discussion.
Similar to the pattern observed with One UI 7, Samsung may eventually introduce the One UI 8 beta program to older devices, including the Galaxy S24 series, Galaxy Z Fold 6, and Galaxy Z Flip 6. However, this expansion may not happen for several months, as seen with the previous beta that started exclusively for the Galaxy S24 lineup in December 2024, before expanding to additional devices in March 2025.
The One UI 8 beta program is set to launch in various regions, with early indications appearing in Samsung’s community forums and Members app for the following countries:
United States South Korea Germany United Kingdom India PolandThese regions are known for their strong beta user bases, providing Samsung with essential feedback for refining their new software.
With the impending release of Android 16, the One UI 8 beta program is expected to officially begin soon. As hints about the program emerge on the Samsung Members app and community forums, users can look forward to beta registrations opening in the coming weeks. Samsung has also established a new Beta Program Home, serving as a centralized hub for all beta-related information.
Once the beta program launches in your region, you can navigate to the Samsung Members app and look for the “One UI Beta Program” banner to enroll and experience the new software firsthand. This new Beta Program Home includes information on the One UI Beta, One UI Watch Beta, App Beta, and various beta tips, allowing users to manage their beta experiences efficiently.
