Samsung Galaxy S23 One UI 9.0 Update Rolls Out in Europe and Asia

Samsung has started pushing the One UI 9.0 software, based on Android 17, to the Galaxy S23 in a limited number of markets, while the Galaxy A36 sees a broader rollout across Europe.

Galaxy S23 One UI 9 Android 17 Availability

The latest One UI 9.0 build brings Android 17 features to the Galaxy S23, but the distribution is not yet global. Early reports indicate that the update is being released in parts of Asia and Europe, with other regions expected to receive it later.

Samsung Galaxy A36 One UI 9 Europe Launch

Following a South Korean debut, the One UI 9 update for the Galaxy A36 is now being rolled out to European users. The package downloads over the air and is roughly 2.38 GB in size, requiring a fast connection for a smooth installation.

Once applied, the device reports software version A366BXXUCDZIF and includes the security patch dated September 5 2026. Samsung has indicated that the rollout will be gradual, so users who have not yet seen the notification should expect it within the coming days.

One UI 9 Release Date and Additional Galaxy Phones

Industry sources note that five more Galaxy models are slated to receive the Android 17‑based One UI 9 update soon, though exact dates have not been confirmed. The staggered release pattern mirrors Samsung's recent approach of launching updates in select markets before a worldwide push.

What Comes Next for Samsung Users?

Customers with supported devices should monitor their notification panels for the update prompt. Those who miss the initial wave can anticipate a later rollout, as Samsung typically expands distribution over several weeks.

While the Galaxy S23 update remains limited, the broader availability of One UI 9 on the Galaxy A36 demonstrates Samsung's commitment to delivering the latest Android experience across its lineup.
