Samsung has commenced the stable rollout of its One UI 9.0 update, based on Android 17, for its Galaxy S26 series smartphones. This marks a significant step for Samsung users, arriving almost five months after the brand initiated its beta program for the latest custom Android interface, as reported by SamMobile.
While the Galaxy S26 series is the first in line to receive the update, Samsung has also provided a clearer roadmap for older flagship models, indicating when owners can expect to upgrade their devices to the new software.
One UI 9 Rollout Schedule Emerges
The stable One UI 9 rollout is now actively underway, with the Galaxy S26 series leading the charge. Specific regional announcements shed more light on the initial deployment:
- In the US, the Galaxy S26, S26 Plus, and S26 Ultra began receiving One UI 9 on September 16.
- Canada’s Galaxy S26 rollout commenced on September 21.
For owners of older devices, Samsung Thailand’s official announcement offers the most detailed schedule to date. According to Android Authority, this roadmap confirms that the Galaxy S25 series, Galaxy Z Fold 7, and Galaxy Z Flip 7 are set to begin receiving the Android 17-based update on September 28. The same announcement indicates that the Galaxy S23 FE will follow sometime in October.
Wider Availability and Regional Variations
It is important for users in Leeds, Yorkshire, and the wider UK to note that while these dates from Samsung Thailand provide the clearest official indication, they are technically specific to that market. Samsung’s rollout messaging has varied by country, meaning exact timing for the UK and other regions will likely differ based on local carriers and specific market schedules. However, the September 28 window for the Galaxy S25 series and last year’s foldables suggests a potential rollout across more markets around the end of September.
Although Samsung’s Thailand announcement did not explicitly mention the Galaxy S24 or Galaxy S23 series alongside the S23 FE, an October window for these flagship generations is considered a reasonable expectation, though not an officially confirmed schedule. The company has stated that One UI 9 will continue to expand gradually to more eligible Galaxy devices beyond the S26 series, paving the way for future innovations, with expectations building for devices like the Samsung Galaxy S27 Ultra, and major announcements often made at events like the Samsung Galaxy Event.
