Beyond just a regular upgrade, One UI 8.0 introduces system-level changes that improve performance, strengthen privacy, and refresh the overall Galaxy experience.

Samsung confirmed that the stable One UI 8.0 update is finally spreading outside Korea. After its successful release on the Galaxy S23 series in Samsung’s home market, users across Africa, Asia, and Europe have begun receiving the update.

Countries such as Australia, Egypt, France, Germany, Malaysia, Spain, Turkey, and Ukraine are among the first to receive the update. The firmware version, S91xBXXU8EYI5, weighs around 3.3GB for the Galaxy S23 Ultra, while the S23 and S23+ come in slightly lighter.
