Samsung Rolls Out New One UI 8.5 Beta for Galaxy S25 Series

Samsung has just released another beta version of One UI 8.5 for its flagship Galaxy S25 series. While this update is notably small in size, its focused nature suggests that Samsung might have identified and addressed a critical issue that required immediate attention.

What’s New in the Galaxy S25 One UI 8.5 Beta?

The latest test version of One UI 8.5 is currently being distributed to the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra models. This new software, identified by the build number ZZAN, weighs in at approximately 553 MB. This is a relatively modest size for a system beta, especially when compared to previous beta releases that often packed a wider range of fixes and improvements.

The official changelog for this update is exceptionally brief, stating only an update to the Bixby assistant version. Users participating in the beta program can download this update through the standard method: by navigating to their phone’s settings and accessing the software update section.

The Significance of a Minimal Update

It’s uncommon for a Samsung beta update to be limited to a single change and such a small data package. This unusual approach could indicate that Samsung needed to urgently resolve a specific bug or problem impacting system performance, one that couldn’t wait for a larger, more comprehensive beta release.

While these are currently speculations, as Samsung has not provided detailed reasons for the immediate release of this particular version, the lack of information regarding security or stability patches adds a layer of mystery to the update.

Understanding One UI and Bixby

For those new to Samsung’s ecosystem, One UI is Samsung’s custom Android skin, providing a distinct user interface and a suite of exclusive features over stock Android. Bixby, on the other hand, is Samsung’s AI-powered virtual assistant, designed to help users with tasks, answer questions, and control their devices using voice commands.

When Can We Expect the Stable One UI 8.5 Release?

It’s important to remember that the stable version of One UI 8.5 is anticipated to debut alongside the new Galaxy S26 series. The launch of the Galaxy S26 lineup is currently planned for February 25, 2026. Following its official introduction with the new generation of smartphones, the One UI 8.5 update is expected to gradually roll out to other compatible Samsung devices.
