Samsung phone owners eagerly awaiting the next major software update might finally have a clearer picture of what lies ahead. A recent regional schedule published by Samsung Thailand has pulled back the curtain on the upcoming rollout plan for One UI 9.0, giving Galaxy users concrete dates for the Android 17-based release.
While major Android updates often roll out in unpredictable regional waves, this detailed schedule offers the best timeline yet for when top Galaxy flagships and fan-favorite devices will see the new software.
Samsung One UI 9.0 Rollout Roadmap
According to the official communication released by Samsung Thailand, the next phase of the One UI 9.0 rollout breaks down as follows:
September 21: Galaxy S26 series
September 28: Galaxy S25 series, Galaxy Z Fold7, and Galaxy Z Flip7
By October: Galaxy S23 FE
The news comes on the heels of Samsung kickstarting the stable One UI 9.0 deployment in its home country. Galaxy S26 series users in South Korea already began receiving the official software push on September 16.
What Regional Timelines Mean for Global Users
It is important to keep in mind that software schedules issued by specific regional branches—such as Samsung Thailand—often serve as localized launch targets. Unforeseen bugs, carrier certifications, and regional testing can cause release dates to vary across North America, Europe, and India.
However, regional roadmaps like this usually signal that the stable firmware is ready for mass deployment. Even if global releases do not land on the exact day specified, nearby markets typically see the update within days or weeks of the initial wave.

What’s Next for the Galaxy Ecosystem?
Samsung is expected to expand the One UI 9.0 update further across its line of smartphones and tablets over the coming weeks. Standard flagship tiers like the Galaxy S24 and Galaxy S23 series, mid-range Galaxy A-series devices, and the Galaxy Tab lineup are all slated to follow as the broader rollout ramps up through the fall.
If you own a recently released Galaxy device, ensure your auto-update settings are toggled on or manually check for available software packages under your phone’s system settings.
