Samsung One UI 9 Update: Android 17 Testing Expands to These Galaxy Smartphones and Tablets

Samsung has reportedly expanded internal testing of its Android 17-based One UI 9 update to a wider range of Galaxy smartphones and tablets. While the public beta remains exclusive to the Galaxy S26 series, new firmware builds suggest the company is actively preparing the software for older flagship phones, foldables, tablets, and select Galaxy A-series devices.

Although this does not confirm rollout dates, it indicates that One UI 9 development is progressing steadily. Samsung is expected to introduce Android 17 alongside its own UI improvements, updated apps, Galaxy AI enhancements, and device-specific features before expanding the rollout to more eligible devices.

Samsung One UI 9 Beta Currently Limited to Galaxy S26 Series

Samsung released the first One UI 9 beta in May for the Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra. The beta programme is expected to continue for several more weeks before the stable rollout begins.

Android 17 first arrived on Google Pixel devices earlier this month, but Samsung has yet to announce an official One UI 9 release timeline or rollout roadmap.

Samsung One UI 9 Internal Testing Devices

Internal Android 17 firmware is reportedly being tested for the following Galaxy devices:

Galaxy S Series

• Galaxy S25
• Galaxy S25+
• Galaxy S25 Ultra
• Galaxy S24
• Galaxy S24+
• Galaxy S24 Ultra
• Galaxy S24 FE

Galaxy Z Foldables

• Galaxy A34
• Galaxy A17
• Galaxy A16

Galaxy Tablets

• Galaxy Tab S11
• Galaxy Tab S11 Ultra
• Galaxy Tab S10+
• Galaxy Tab S10 Ultra

Upcoming Samsung Devices Could Debut with One UI 9

The report also mentions firmware development for several unreleased Galaxy devices, including:

• Galaxy Z Fold 8
• Galaxy Z Fold 8 Ultra
• Galaxy Z Flip 8
• Galaxy Tab S12+
• Galaxy Tab S12 Ultra
• Galaxy A18

These devices are expected to launch with Android 17 and One UI 9 pre-installed. Samsung's next-generation foldables are rumoured to debut in late July, potentially becoming the first devices to ship with the new software out of the box.

What Galaxy Users Should Expect

Internal testing does not guarantee an immediate public rollout. Samsung typically prepares firmware for multiple devices months in advance before deciding beta availability, regional rollout schedules, and stable release dates. Carrier certification and device-specific optimisation can also affect deployment timelines.

The current list should be viewed as an early indication of Samsung's One UI 9 plans rather than a final eligibility list. More Galaxy smartphones and tablets are expected to join the testing programme as development progresses, with a clearer rollout roadmap likely to be announced after the beta expands beyond the Galaxy S26 lineup.
