Samsung's One UI 9.5 beta looks close to launching
A One UI 9.5 test build for the Galaxy S26 Ultra has appeared on Samsung's servers, which usually comes just before beta sign-ups open.
The facts
- According to Engadget, a One UI 9.5 beta build (firmware S948BXXU6ZZK3) for the Galaxy S26 Ultra has appeared on Samsung's Korean and US update servers.
- Samsung has not announced the beta or a date. Its last point-five update, One UI 8.5, opened to testers on December 8 2025.
- One UI 9.5 is still based on Android 17 and is expected to launch with the Galaxy S27 early in 2027. SammyFans guesses early December for the beta, while SamMobile thinks November.
- Last time the beta ran in six countries: Germany, India, Poland, South Korea, the UK and the US. In the US it was only for unlocked phones, so carrier-locked S26 owners may have to wait for the stable release.
Case notes · Danny's take
Why it matters
A build on the servers is evidence. A rumour on a fan site is not. Samsung has stayed quiet, but its update pattern points to a beta soon. If you're in Lagos, Nairobi or Accra, note that no African country was on last time's list. Most readers here will get One UI 9.5 only when the stable version lands. Beta software is a trade: early features for the risk of losing data.
