Samsung One UI 8 rollout schedule leaks for Galaxy phones, tablets, and watches

Samsung’s One UI 8 rollout is finally taking shape, and the leaked schedule gives Galaxy fans a clearer idea of when they can expect the stable Android 16-based interface on their phones and tablets. While Samsung has been testing the beta version across a range of devices, owners of both flagships and mid-range models have been waiting anxiously for the official release.

The company hasn’t formally announced the update dates, but the leaked roadmap provides a fairly detailed timeline.

The first wave: Galaxy S25 series leads the rollout

The Galaxy S25 lineup – including the S25, S25+, and the powerful Galaxy S25 Ultra – will be the very first to receive One UI 8. According to the leak, the update begins rolling out on September 18. A week later, starting September 25, Samsung plans to update the Galaxy S25 Edge, the entire Galaxy S24 family (including the S24 FE), and mid-range contenders such as the Galaxy A56 5G and Galaxy A36 5G.

October brings updates to tablets, watches, and more phones

October looks to be the busiest month in the rollout. On October 1, the Galaxy Tab S10+ and S10 Ultra (both Wi-Fi and 5G variants) will receive One UI 8, alongside the Galaxy Watch7 and the Galaxy Watch6 lineup, including the Classic and FE editions. Then on October 2, updates will reach the Galaxy S23 series, Galaxy S21 FE, the new Galaxy Z Fold6 and Z Flip6, and several affordable A-series devices like the A26 5G, A17 5G, and A16 5G.

The rollout continues throughout the month with key milestones: the Galaxy S22 family and the Galaxy Z Fold4/Flip4 on October 6, followed by the Galaxy Tab S10 FE range on October 9. Later in the month, foldables like the Galaxy Z Fold5 and Flip5, popular mid-rangers such as the A54 5G and A52s 5G, and tablets like the Galaxy Tab S9 FE series are set to join the party.

By mid-to-late October, more affordable devices like the Galaxy A25 5G, A23 5G, A15 5G, and budget M-series phones (M34 5G, M33 5G, and M15 5G) will follow. Samsung also plans to update rugged and enterprise-focused devices, including the Galaxy XCover 6 Pro, XCover 7, and the Galaxy Tab Active 5 series. Toward the end of the month, the massive Tab S9 family and older Tab S8 lineup will also get the new firmware.

November closes the rollout with wearables and tablets

The schedule suggests the final phase lands in November. The Galaxy Watch5 Pro, Watch5, and the Watch4 series are due on November 3. A few days later, the Galaxy Tab A9 will receive its update on November 5, followed by the Galaxy Tab Active 5 Pro 5G on November 7. The last device on the leaked list is the rugged Galaxy XCover 7 Pro, which should receive One UI 8 on November 10.

Important caveats and regional limitations

It’s important to remember that leaked schedules aren’t official guarantees. Samsung has a history of adjusting its timelines depending on testing, carrier approvals, and unexpected bugs. The source also clarified that this roadmap applies only to select regions, particularly parts of Asia, and may not cover every eligible device worldwide. As always, rollout speed will depend on your location and carrier, so some users may see the update sooner while others wait longer.

What One UI 8 means for Galaxy users

Beyond the rollout dates, One UI 8 itself promises to be a significant step forward. Built on Android 16, it brings smoother animations, enhanced privacy settings, deeper customization, and performance boosts tailored to both high-end flagships and budget-friendly devices. Samsung is also expected to improve battery efficiency across its ecosystem, refine multitasking tools for foldables and tablets, and deliver tighter integration with the Galaxy Watch lineup.

Community reactions and lingering questions

Samsung’s fans are cautiously optimistic. Some are thrilled to see timely updates extending to tablets and even rugged devices, while others are skeptical about whether older models will truly make the cut. For instance, owners of the Galaxy A52s 5G are already debating online whether their phone will be left behind. Since it launched with Android 11 and has already received three major updates, reaching Android 14 with One UI 6.1, it’s unlikely to be upgraded further. That reality highlights Samsung’s update policy: while many mid-rangers now receive four years of updates, devices released before this new commitment may hit their limit sooner.

In the end, this leak paints a picture of an ambitious but staged rollout, where Samsung is prioritizing its latest flagships while gradually covering tablets, wearables, and more affordable handsets. Whether the actual timeline matches the leak remains to be seen, but for Galaxy owners eager to try One UI 8, September through November could be a season of steady software upgrades.
