Samsung has initiated the One UI 8.5 beta program for the Galaxy S25 series in select regions, and is concurrently developing the firmware for various other devices. Notably, the Galaxy M series, previously absent from the confirmed list, is now included in this development phase. A test build for the Galaxy M54, indicating the forthcoming update, has been identified in several markets such as the United Arab Emirates, Malaysia, Saudi Arabia, and Thailand. These regions typically host the Galaxy M series, which rarely sees release in North America. Samsung plans to expand the availability of test builds for the Galaxy M and other devices, although a stable release of One UI 8.5 for these models is not expected imminently.
