Samsung has now officially closed the One UI 8.5 beta program for the Galaxy S24 lineup in the UK. This strongly suggests that a wider stable rollout for all users could begin globally very soon.
The update appears to focus on overall system optimization, smoother animations, improved battery efficiency, refined Galaxy AI features, and better stability across Samsung apps and services.
T-Mobile Galaxy S24 Users in the US Also Receiving Stable Update
In another major development, T-Mobile users in the United States have also started receiving the stable One UI 8.5 firmware for the Galaxy S24 series.
This confirms Samsung is rapidly expanding the rollout beyond Europe, with carrier-locked models now entering the stable deployment phase. Historically, once T-Mobile builds begin rolling out, unlocked US variants and additional carriers tend to follow shortly afterward.

Galaxy S23 Series Joins the Stable One UI 8.5 Rollout
Samsung is not limiting the stable rollout to its newest flagship lineup. The company has now also started pushing the stable One UI 8.5 update to Galaxy S23 beta users in Korea.

- Samsung Galaxy S23 Ultra
Galaxy S23 Stable Build Versions
- S918NKSU7FZDT

The Korean rollout is often Samsung’s first phase before expansion to additional international markets including India, Europe, and North America.
What’s New in One UI 8.5?
While Samsung has not published a complete changelog yet, One UI 8.5 is expected to introduce:
- Smoother system animations
- Faster app opening speeds
- Better RAM management
- Improved standby battery life
- Updated Galaxy AI enhancements
- Refined lock screen and quick settings UI
- Better thermal management during gaming
- Android 16 privacy and security improvements
Samsung also appears to have optimized background processes significantly, making the overall experience feel more responsive compared to previous One UI builds.
When Will Other Regions Get the Update?
Based on Samsung’s rollout pattern, more regions including India, Germany, UAE, and other European countries are expected to receive the stable One UI 8.5 update very soon.
Users who participated in the beta program will likely receive the update first, followed by stable users in phased batches over the next few days.
Samsung’s faster rollout strategy this year suggests the company is trying to accelerate Android 16 adoption across eligible Galaxy devices much earlier than previous generations.
