Samsung Releases Third One UI 8.5 Beta for Galaxy S25 Series with Key Fixes
Samsung has initiated the rollout of the third beta version of One UI 8.5 for its flagship Galaxy S25 series, including the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra. This update, based on Android 16 QPR2, brings several important bug fixes and the latest January 2026 security patch as Samsung continues to refine its software ahead of the Galaxy S26 series launch.
What's New in One UI 8.5 Beta 3
The third beta release addresses multiple issues that users encountered in previous versions. The most notable fixes include resolving a clock display error on the lock screen that affected some devices. Additionally, Samsung has improved performance in the gallery app, specifically reducing lag when using Live Effects features.
Battery optimization receives attention in this update, with improvements to high power consumption issues that occurred when specific applications were running. The update also enhances the visibility of the search button on the widget addition screen and resolves problems with favorites in the phone app. Another fix addresses an issue where Now Briefing failed to display properly.
Regional Availability and Rollout
The firmware update, carrying version ZZA3, is currently available in several key markets. Initial reports indicate the beta is live in South Korea, Germany, the United Kingdom, and India. In some regions, including India, this represents the second beta version rather than the third, suggesting staggered regional testing approaches.
Additional markets, including the United States and Poland, are expected to receive the update shortly. Samsung typically expands beta programs gradually, allowing for regional testing and feedback collection before wider deployment.
Security and Performance Improvements
Alongside the bug fixes, the update includes the January 2026 Android security patch. While specific details about the security vulnerabilities addressed haven't been disclosed yet, monthly security updates remain a critical component of Samsung's software maintenance strategy, particularly for flagship devices.
The One UI 8.5 beta program represents Samsung's ongoing commitment to software refinement, with the company testing new features and improvements on current-generation devices before the official launch with next-generation hardware. This approach allows for real-world testing and user feedback collection that can improve the final software release.
Conclusion
The third One UI 8.5 beta for the Galaxy S25 series demonstrates Samsung's responsive approach to software development, addressing user-reported issues while maintaining regular security updates. As the company prepares for the Galaxy S26 series launch with One UI 8.5, these beta releases provide valuable testing ground for new features and optimizations. Users participating in the beta program can expect continued refinements as Samsung works toward a stable public release.
