Samsung has officially launched the final version of the One UI 9.0 interface, based on Android 17, for the Galaxy S25, S25 Plus, and S25 Ultra smartphones in Europe. The rollout follows previous releases in South Korea and the United States.
The European firmware version is identified as S93xBXXUCDZIF. Participants in the beta testing program are the first to receive the update, with a download size of approximately 550 MB. For users currently running One UI 8.5, the update package is expected to exceed 3 GB.
The distribution process is being conducted in stages, meaning availability may vary across different European countries and individual devices. Samsung advises users to ensure their battery level is at least 30% and to perform a data backup before initiating the installation.
