One UI 9.5 beta build appears on Samsung servers
A One UI 9.5 beta build for the Galaxy S26 Ultra has appeared on Samsung’s servers in South Korea and the US.
Samsung has not announced when testing will begin, but server listings have often appeared shortly before the company opens registrations.
The detected build is for the S26 Ultra, though other Galaxy phones may also be included later.
The beta is expected to use Android 17 and arrive ahead of One UI 9.5’s anticipated release with the Galaxy S27 in early 2027.
Registration is expected through the Samsung Members app, followed by a download from the phone’s software update settings.
The previous beta was limited to six countries—Germany, India, Poland, South Korea, the UK and the US—and carrier-locked US phones may not qualify.
Samsung has not confirmed eligible phones or a sign-up date, so interested users will need to wait for an official announcement.
