Samsung hasn’t announced the next phase of the beta yet. Still, there are now enough signs to suggest that more phones are about to join.

One UI 9 beta is ready to expand
That usually happens shortly before a beta program goes live.
The list includes:
Galaxy S series
- Galaxy S25
- Galaxy S25+
- Galaxy S25 Ultra
- Galaxy S25 FE
- Galaxy S24
- Galaxy S24+
- Galaxy S24 Ultra
- Galaxy S23
- Galaxy S23+
- Galaxy S23 Ultra
Galaxy Z series
- Galaxy Z Fold 7
- Galaxy Z Flip 7
Galaxy A series
- Galaxy A57
- Galaxy A56
- Galaxy A55
- Galaxy A54
- Galaxy A36
- Galaxy A35
There is one thing to keep in mind. This isn’t an official list from Samsung, and finding a beta build on its servers doesn’t mean every phone above will join the public beta program.
Even the Galaxy A54 is there
What surprised me more is the number of Galaxy A phones on the list. Samsung usually starts with its expensive Galaxy S and Z models before moving down to the A series.
One UI 9 is based on Android 17 and brings several changes to Galaxy phones. Samsung has added more customization options, new security tools and updates to several of its own apps. AI is also a big part of the release, although some of the more advanced features won’t be available on every Galaxy device.
The stable version already ships on Samsung’s new Galaxy Z Fold 8 and Z Flip 8, while the Galaxy S26 series should get it soon.
For now, Samsung hasn’t said when the wider beta will begin. But with beta pages already appearing on its Community forum, Galaxy S25 and recent Fold and Flip owners may not have much longer to wait.
