Stable One UI 8 Rollout Schedule For All Samsung Devices
Samsung Galaxy users, the wait is almost over! A comprehensive leaked roadmap has surfaced revealing the complete rollout schedule for One UI 8 (Android 16) across Samsung’s entire device ecosystem. This unofficial but promising timeline spans from September through October 2025, covering everything from flagship phones to tablets and smartwatches.
When will Stable One UI 8 Rollout?
The Flagship First Wave: September 18-25
Samsung is prioritizing its newest and most premium devices in the initial rollout phase. The Galaxy S25 series leads the charge on September 18, 2025, with the S25, S25+, and S25 Ultra receiving the stable One UI 8 update first. Interestingly, the new Galaxy A56 5G will also be part of this premium launch wave.
Just one week later, on September 25, Samsung will expand the rollout to include the still-popular Galaxy S24 series (S24, S24+, S24 Ultra, and S24 FE), along with the rumored S25 Edge and several A-series devices including the A36 5G.
October: The Mass Rollout Begins
October represents the most significant phase of Samsung’s One UI 8 deployment strategy. The schedule reveals a carefully orchestrated rollout designed to minimize server load while ensuring broad compatibility testing:
October 1 marks the beginning of wearables support, with Galaxy Watch models (FE, Watch7, Watch6, Watch6 Classic) and tablets (Tab S10+, Tab S10 Ultra) receiving their updates.
October 2 brings One UI 8 to the Galaxy S23 series, foldables (Z Fold6, Z Flip6), and additional A-series devices, representing a major milestone for millions of users worldwide.
Legacy Device Support and Notable Exclusions
The roadmap reveals both generous support for older devices and some disappointing exclusions. The Galaxy S22 series will receive One UI 8 on October 6, which represents the final major Android update for these devices, though users can expect One UI 8.5 as a subsequent release.
Notably absent from the list is the regular Galaxy S21, marking the end of major updates for this once-flagship device. However, the S21 FE will continue receiving support through October 16, demonstrating Samsung’s commitment to its Fan Edition lineup.
Tablet and Wearables
Samsung’s commitment to its broader ecosystem shines through in this rollout. The Galaxy Tab lineup receives extensive support, from the premium Tab S10 series to the budget-friendly Tab S6 Lite. Even the affordable Galaxy Tab A9 surprisingly makes the list, showing Samsung’s dedication to keeping older budget devices current.
Smartwatch support extends across multiple generations, with devices as old as the Galaxy Watch4 receiving Android 16 support. This creates an interesting situation where some watches will receive newer software than certain phones released around the same time.
Regional Variations and Timeline Expectations
While this roadmap provides specific dates, users should expect regional variations in deployment. Historically, Samsung rolls out major updates in phases, starting with select markets before expanding globally. Canadian and European users typically see updates 1-2 weeks after the initial launch dates.
