Samsung Begins One UI 9 Tests for Galaxy A24 4G

If you own a Galaxy A24 4G, something quietly moved behind the scenes this week. Samsung pushed the Android 16-based One UI 8.5 stable build only days ago, and engineers are already poking at Android 17 on the same handset.

Testing build A245FXXUCGZF4 has been spotted on Samsung's servers. It’s an early breadcrumb, not a release note. That firmware ID suggests One UI 9 work is under way for the A24 4G, though Samsung hasn’t announced a beta program or a rollout timetable for this model.

Who’s in the club so far, and who’s next

Right now, the One UI 9 beta is largely a flagship affair. Only Galaxy S26 phones have seen beta builds to date. That tells you Samsung is validating the new software on its newest hardware first. Makes sense. Big changes need big testbeds.

• Galaxy Z Flip8
• Galaxy Z Fold8
• Galaxy Z Fold8 Ultra

Rumors say Samsung plans to ship One UI 9 out of the box on its upcoming foldables, with a launch event rumored for July 22 in London. If that timeline holds, foldables will lead, and midrange models like the A24 will follow once the company stabilizes the code across more devices.

So what should A24 owners expect? Patience and incremental updates. Beta invites could expand, or Samsung might skip a public beta for some A-series phones and push straight to a stable release after internal testing. Either way, seeing a server-side firmware entry this early is a good indicator that Android 17 work is moving along.

Watch the update channels and Samsung’s official announcements. When the A24 4G gets its One UI 9 build in users’ hands, we’ll know whether Samsung tuned Android 17 for midrange hardware or left heavy features to the foldables and flagships.
