Samsung is beginning trials of One UI 9 on two additional smartphones.
Samsung is making progress in enhancing One UI 9, an interface built on Android 17. The upcoming update is expected to be available for various Samsung smartphones in the near future. Following beta tests for the Galaxy S26 series, the company is now working on integrating the new software into other device models, including the Galaxy A57 and Galaxy A17 5G.

The introduction of these firmwares marks a new phase in the evolution of One UI 9. Samsung conducts internal testing to confirm the software’s performance on all eligible devices before releasing updates to the public. Subsequently, they release beta versions.

The beta program is currently limited to the Galaxy S26 series in specific markets, but newer mid-range models like the Galaxy A57 may join in future testing phases. The Galaxy A17 5G will receive the stable version once the distribution is expanded.

One UI 9 is anticipated to be unveiled on July 22 at the upcoming Galaxy Unpacked event, along with the introduction of new foldable Samsung phones featuring the new interface. Samsung has not made any official announcements yet.
