After releasing the  One UI 8.5 beta program for the Galaxy S25 series today, the Samsung Galaxy S25 FE smartphone has now been added to the One UI 8.5 internal testing device group. Along with the One UI 8.5 beta program, the Korean tech giant is also working on preparing this major update for other Galaxy devices.

One UI 8.5 Beta introduces numerous new features, enhanced Galaxy AI tools, an improved user interface, and improved productivity, privacy, and performance across the Galaxy ecosystem. As you receive the Beta build, you may encounter bugs and battery-draining issues.

Tarun Vats has spotted a new One UI 8.5 testing firmware version, S731BXXU3BYLD, for the Samsung Galaxy S25 FE. The Galaxy S25 FE launched with One UI 8.0 pre-installed, and the One UI 8.5 update will be the minor One UI upgrade.

The One UI 8.5 beta update is currently available in only a few countries for the Samsung Galaxy S25, Galaxy S25 Plus, and Galaxy S25 Ultra. This lets users try out new features before the stable release. A new testing build suggests that Samsung Galaxy S25 FE users will receive this major update directly when the stable version is released.

In addition, Samsung has also confirmed that it will launch the Galaxy S26 series next year with the One UI 8.5 update Pre-installed. This means that Galaxy S25 FE users will receive this major update sometime afterward.

Samsung has begun rolling out the One UI 8 Watch update for the Galaxy Watch 4, Galaxy Watch 4 Classic, and Galaxy Watch 5 LTE. The  One UI 8 Watch update is based on the Wear OS 6.

Note that the stable One UI 8 Watch update is currently available only to Galaxy Watch 4 users in South Korea. The company has not yet provided a timeline for when this update will be available in the global market.

However, the Galaxy Watch 5 LTE is already receiving the One UI 8 Watch update in India. Given the pace of the One UI 8 update rollout, it shouldn’t be long before it becomes widely available.

Galaxy Watch 4, Watch 4 Classic, and Galaxy Watch 5 LTE users can identify the latest software via the PDA build version ending with JYK4 and DYK4, respectively. The firmware also carries the October 2025 security patch. The stable update unlocks even better performance, power efficiency, and stability.

One UI 8 Watch brings a completely new tile system that improves accessibility. This update also optimizes overall performance and battery efficiency with app updates. You can look forward to a whole new world of smartwatch ventures.
