Samsung starts developing One UI 9.5 for Galaxy S25

We expect the brand to open a beta program of the new software for the lineup before releasing its stable build.

TL;DR

Samsung is already developing One UI 9.5 for the Galaxy S25 series, even though One UI 9.0 is still rolling out to eligible devices.

A One UI 9.5 firmware build for the Galaxy S25 Ultra has appeared on Samsung's servers, but no other details are available yet.

Leaks suggest UI changes and new features are coming, and Samsung is expected to run a beta before the stable release.

Although Samsung hasn’t completed the rollout of its latest custom Android interface for Galaxy smartphones, One UI 9.0 (Android 17), to all eligible devices, the brand already appears to be in the advanced stages of developing its next iteration, One UI 9.5. Now, it looks like the company has started developing the new software for the Galaxy S25 series as well.

A firmware file for the Galaxy S25 Ultra featuring One UI 9.5 has been spotted on Samsung’s servers. It carries the firmware version S938BXXUDEZKG (via Fahad Ali Javed). Unfortunately, there’s no other information available on the matter at the moment.

Leaks about One UI 9.5 have given us a pretty good idea of what to expect from the upcoming software. Additionally, we have discovered new versions of several Samsung apps designed for One UI 9.5, revealing various UI changes and new features.

We expect Samsung to launch the One UI 9.5 beta program before releasing the stable update. However, there is no information yet on when the company plans to kick off the beta program.
