Samsung is running internal tests of One UI 9.0, its Android 17-based software update, on at least 37 Galaxy devices. This is happening in parallel with the public beta program, which is currently limited to Galaxy S26 owners. According to SammyFans, the internal testing list includes phones, foldables, and tablets across multiple product lines, including some budget models that rarely get this kind of early attention.
The official debut of One UI 9 is expected in late July, tied to Samsung’s Galaxy Unpacked event. The actual rollout to the public will take a few more weeks after that, starting with newer devices first. Samsung has already pushed three beta builds to Galaxy S26 users across six countries since the beta program started in mid-May.
The public beta is limited to three devices right now: the Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra. But behind the scenes, Samsung’s internal testing is much broader, and that tells us a lot about how aggressively the company plans to push this update out once the official launch window opens.
The range of devices in internal testing is worth noting. It covers the last three generations of Galaxy S flagships, the Z Fold and Z Flip foldable lines going back to the 5th generation, and a broad range of Galaxy A series phones. That last category is particularly interesting. Budget-tier devices like the Galaxy A07 and A17 making the internal testing list suggests Samsung intends to push One UI 9 down to more affordable hardware faster than it has in previous cycles.
Here is the full list of devices currently in Samsung’s internal One UI 9.0 testing:
- Galaxy S Series: S25, S25+, S25 Ultra, S24, S24+, S24 Ultra, S24 FE, S23, S23+, S23 Ultra, S23 FE
- Galaxy Z Series: Z Fold 7, Z Flip 7, Z Fold 6, Z Flip 6, Z Fold 5, Z Flip 5
- Galaxy A Series: A57, A37, A17, A07, A56, A36, A26, A16, A55, A35, A25, A54, A34, A24
- Galaxy M Series: M35, M56
- Galaxy Tab S Series: Tab S11, Tab S11 Ultra, Tab S10+, Tab S10 Ultra
This comes in the context of Samsung’s two-tier update policy, which guarantees seven years of updates for flagship devices (Galaxy S24 and newer) and six years for everything else. That policy gives Samsung a strong reason to test widely and roll out consistently. Skipping lower-end devices or rolling out slowly would undercut those commitments in a very visible way.
The internal list is also not final. Samsung is expected to add more models as testing progresses. A broader beta program opening to more users is possible, but only after the Galaxy Unpacked event scheduled for late July. That event is also expected to introduce the Galaxy Z Fold 8, Z Flip 8, Galaxy Watch 9, and Watch Ultra 2, all of which will ship with One UI 9 out of the box.
For existing Galaxy owners, the key takeaway is simple: if your device is from the past three to four years and falls within Samsung’s update window, there is a good chance One UI 9 is already being tested on it internally. The stable rollout timeline will depend on how smoothly those tests go between now and the Unpacked event.
