Samsung Expands One UI 8.5 Beta, Galaxy M54 Now in Testing Phase

Samsung has begun testing its next major software update on a new device. The Galaxy M54 smartphone has been spotted running an early One UI 8.5 build. This development was confirmed this week in several key markets.According to a report from SamMobile, the test firmware is now live on servers. It marks the first Galaxy M series phone confirmed for the One UI 8.5 update path. This move signals Samsung’s commitment to bringing its latest software to more affordable lineups.

Limited Regional Rollout for Initial Beta Phase

The current One UI 8.5 test build for the Galaxy M54 is not globally available. It has been identified in specific regions including the United Arab Emirates, Malaysia, and Saudi Arabia. Thailand and several other markets are also included in this early phase.This regional focus is standard for Samsung’s M-series devices. These phones are typically not released in North America or parts of Europe. The beta availability aligns with the device’s official sales markets.Samsung will likely upload more test builds for the Galaxy M54 soon. Other M-series models are expected to follow in the coming weeks. The company uses this phased testing to identify and fix bugs before a public release.

Stable Release Expected Much Later in 2025

Consumers should not expect the final software immediately. The stable version of One UI 8.5 is predicted to launch alongside the Galaxy S26 series. That launch is tentatively scheduled for March of next year.Even after that, Samsung’s flagship phones will receive the update first. The Galaxy S and Z series models are always prioritized. More budget-friendly models like the M54 traditionally receive major updates several months later.This staggered schedule ensures stability across all device tiers. It allows Samsung to refine the software based on flagship feedback. Galaxy M54 users can likely anticipate the update in the second half of 2025.
