Samsung started rolling out Android 17-based One UI 9 with the Galaxy Z Fold 8 and Flip 8 in July 2026. The Galaxy S26 series is now receiving the stable build, and a September 28 date has surfaced for the Galaxy S25. When will the Galaxy S25 get One UI 9? Does that date apply outside Thailand?

What Is the Confirmed One UI 9 Date for the Galaxy S25?

Samsung Thailand announced that the Galaxy S25 series, Galaxy Z Fold 7 and Galaxy Z Flip 7 will start receiving One UI 9 on September 28. That date is specific to Thailand and should not be read as a worldwide schedule. Rollouts usually vary by country and carrier, so other regions may see the update earlier or later. Treat September 28 as a signal that the S25 wave is close, not as a global deadline.

The same announcement pointed to October for the Galaxy S23 FE. The Galaxy S24 and S23 series have no confirmed dates yet, and October is only an expectation. Galaxy A-series models follow their own staggered timeline.

Which Galaxy Devices Are Getting One UI 9?

One UI 9 debuted on the Galaxy Z Fold 8 and Flip 8 in July 2026, and the Galaxy S26 series received the stable update in South Korea on September 16. Reports say the global S26 rollout began on September 21 in markets such as Germany, India, Poland, the UK and the US. Samsung’s newsroom list covers the families below, though it is not exhaustive.

The Galaxy Z Fold 7 and Flip 7, Z Fold 6 and Flip 6, and Z Fold 5 and Flip 5.

How Do You Join the One UI 9 Beta?

The One UI 9 beta for the Galaxy S25 started in India and South Korea, and later beta builds have followed. Samsung has not said whether other regions can join. If your phone and region qualify, the steps below apply.

Open the Samsung Members app and look for the One UI 9 beta registration.
Join the program if your model and region are supported.
Go to Settings and open Software update.
Download and install the beta build when it appears.

Betas can bring app crashes, extra battery drain and heat. Use them on a spare phone instead of your main device.

The clearest date for the Galaxy S25 is September 28, but it belongs to Thailand. Everyone else should wait for country and carrier announcements before planning around it. Checking Samsung Members and the Software update menu is the safest routine. Has your Galaxy S25 received a One UI 9 notice yet?
