Samsung May Test One UI 9 Beta on Galaxy A35 and A56

Something is stirring behind Samsung's curtains. Firmware traces for One UI 9 beta have been spotted for the Galaxy A35 and Galaxy A56, suggesting the company might open beta channels for midrange phones before pushing a wider stable rollout.

Why does this matter? Because beta builds often reveal the rollout strategy long before an official timetable. In this case, Samsung’s internal test servers in Korea show firmware entries A356NKSUAZZH5 for the A35 and A566SKSU9ZZHH for the A56. That’s not a rumor from a forum thread — those are build IDs tied to Samsung’s ecosystem. Samsung has even created a One UI 9 beta community forum thread for the Galaxy A56 on Samsung Community India, which hints at imminent wider testing.

Not every Galaxy is waiting in line. A handful of phones launched with One UI 9 already: the Galaxy Z Fold8, the Galaxy Z Fold8 Ultra, the Galaxy Z Flip8 and the Galaxy S26 FE. The Galaxy S26 series has been the focus of multiple beta shipments — seven updates so far — and it looks likely they’ll receive the stable Android 17-based One UI 9 in the coming weeks.

So what comes next? Samsung tends to stagger releases: flagship betas first, broader testing later. But spotting beta firmware for the A35 and A56 suggests a slightly different order this time. It’s plausible Samsung will open a beta track for these midrange models while finalizing stable builds for the S26 family. In other words: beta on midrange. Stable for flagships. It’s an interesting reversal.

Will the S25 line and other eligible devices follow? Probably. Once Samsung nails the stable S26 release, the company typically expands beta invites to more models. Expect the S25 series and a larger batch of Galaxy phones to appear on One UI 9 test lists soon.

If you own a Galaxy A35 or A56, check the Samsung Members app and your region’s community page — the beta door might open before you know it.

Keep your device backed up. And keep watching for the next build ID to tell the real story.
