Samsung is internally testing Android 17-based One UI 9 for several Galaxy devices, including the Galaxy S25 series. However, the Korean company has released the One UI 9 beta only for the Galaxy S26 lineup so far. The good news is that the Galaxy S25 series could receive the One UI 9 beta soon.
The first One UI 9 beta build for the Galaxy S25 Ultra has been spotted on Samsung’s server with firmware version S938NKSUBZZG8/S938NOKRBZZG8/S938NKSUBDZG8. This build is specifically for the Korean model of the S25 Ultra, so the beta rollout is expected to begin in South Korea first before expanding to other regions.
What to Expect from One UI 9 Beta
One UI 9, based on Android 17, promises significant improvements in performance, customization, and security. Samsung has been refining the user interface with smoother animations, enhanced multitasking, and deeper integration of Galaxy AI features. The beta program allows early adopters to test these features and provide feedback before the stable release.
Key Features in One UI 9
- Enhanced Galaxy AI: Improved AI-powered tools for photography, productivity, and personalization.
- Refined UI Elements: Smoother transitions, updated icons, and a more intuitive settings menu.
- Better Multitasking: Enhanced split-screen and pop-up view functionality.
- Security Upgrades: Android 17’s built-in security features, including improved app permissions and data protection.
- Performance Optimizations: Faster app launches, reduced lag, and better battery management.
Rollout Timeline for Galaxy S25 Series
Based on the spotted firmware, the One UI 9 beta for the Galaxy S25 Ultra is likely to launch within the next few weeks. Samsung typically follows a phased rollout, starting with the Korean model and then expanding to other markets like the US, Europe, and Asia. The Galaxy S25 and S25+ are expected to join the beta program shortly after the Ultra variant.
How to Join the One UI 9 Beta
To participate in the beta program, users need to have a compatible Galaxy S25 series device and enroll through the Samsung Members app. The beta is usually available on a first-come, first-served basis, with limited slots. Once enrolled, users will receive the beta update over the air (OTA).
Comparison with Galaxy S26 Beta
The Galaxy S26 lineup has already received the One UI 9 beta, giving users a sneak peek at the new features. While the S26 series benefits from newer hardware, the S25 series will still see significant improvements in software performance and AI capabilities. Samsung is likely to optimize One UI 9 for the S25’s Exynos and Snapdragon chipsets.
Potential Issues in Beta Builds
Beta software often comes with bugs and stability issues. Users should be prepared for potential app crashes, battery drain, or UI glitches. Samsung typically releases multiple beta builds to address these issues before the stable version.
Conclusion
The Galaxy S25 series is poised to receive the One UI 9 beta soon, starting with the Korean model of the Galaxy S25 Ultra. This update will bring Android 17 features and Samsung’s latest enhancements. Keep an eye on the Samsung Members app for enrollment opportunities.
