Samsung has begun rolling out the fourth beta version of One UI 8.5 to Galaxy S25 series devices as the company prepares for the official release of the stable version alongside the Galaxy S26 series later in february 2026. This latest beta focuses on improving software stability, fixing bugs, and introducing a notable user‑facing feature.
1. What’s New in One UI 8.5 Beta 4
Major Feature: Direct Voicemail
One of the most notable additions in Beta 4 is the Direct Voicemail feature. This enhancement allows users to:
- Send calls directly to voicemail after a set time period.
- View live transcriptions of voicemails in real time within the samsung phone app.
- Listen to and even answer calls while a voicemail is being recorded.
The feature works entirely on the device and doesn’t depend on carrier infrastructure, giving Galaxy users added flexibility in handling calls.
2. Enhanced Stability and Bug Fixes
Beta 4 primarily focuses on fixing issues reported in earlier beta builds to ensure a more polished experience ahead of the stable rollout. Key improvements include:
- Fixing issues related to search history in the phone app.
- Troubleshooting problems with Bluetooth headset call switching.
- Correcting a lock screen clock shift bug.
- Addressing quirks with AI Select features.
In addition to these functional fixes, samsung has also included the February 2026 Android security patch in this build, enhancing overall system security.
3. Visual and UI Refinements
While most changes in Beta 4 are behind the scenes, there are some visual tweaks worth noting:
- The charging animation has been redesigned — now with a smaller and more refined pill shape and updated color tones that better match One UI’s visual style.
- Some users are also reporting improvements to smoothness in core UI interactions like One UI home animations.
These refinements help make the interface feel more cohesive and responsive.
4. Rollout Details and Availability
The Beta 4 update is currently rolling out to Galaxy S25, S25+, and S25 Ultra devices enrolled in Samsung’s One UI 8.5 beta program. It’s already available in several key regions including South Korea, India, the United States, the United Kingdom, and Germany.
At around 1.5 GB in size, the update reflects both big system enhancements and critical fixes. Users can install it by navigating to Settings > software update > Download and install on their enrolled devices.
5. Preparing for the Galaxy S26 Series
Samsung appears to be using Beta 4 as one of the final polishing stages before the official launch of One UI 8.5 with the upcoming Galaxy S26 lineup. Reports indicate the S26 series is expected to debut during Samsung’s Unpacked event later this month, likely around February 25, 2026 — and it should arrive with the stable version of One UI 8.5 pre‑installed.
Once the stable build is released, samsung will then begin rolling it out to all eligible devices, starting with the latest flagship models and eventually expanding to other Galaxy phones over the weeks following the official release.
Conclusion: Beta 4 Brings Stability and Usefulness
The One UI 8.5 Beta 4 update underscores Samsung’s commitment to refining its software before the major Galaxy S26 launch. With enhanced voicemail capabilities, system optimizations, bug fixes, and updated security patches, this beta brings a more reliable and usable experience for Galaxy S25 users testing the upcoming interface.
