Samsung’s One UI 9.0, based on Android 17, debuted alongside the new Galaxy Z Fold 8 foldable lineup. The update will roll out to older devices over the coming weeks, but for 19 Samsung phones and tablets, this will be the final major OS upgrade. After One UI 9.0, those models will only receive security patches on Samsung’s regular schedule. Here’s the full list of affected devices and what it actually means for their owners.

What you need to know

  • 19 Samsung models — including the Galaxy S23 series, Z Fold 5, Z Flip 5, and Tab S9 family — will receive One UI 9.0 (Android 17) as their last major OS update.
  • Samsung will continue delivering security updates for at least another year after the final OS upgrade, and typically longer for flagships.
  • Some of these devices may still receive One UI 9.5 in 2027, bringing interface and feature improvements on top of the same Android 17 base.
  • One UI 9.0 launched first on the new Galaxy Z Fold 8 and will reach older eligible devices in the weeks ahead.

One UI 9.0 arrived with the Galaxy Z Fold 8

One UI 9.0 on Android 17 was unveiled at Samsung’s presentation of its new foldable smartphones, including the Galaxy Z Fold 8, Fold 8 Ultra, and Flip 8. As is typical, the new firmware ships first on the latest flagships and then rolls out to previous-generation devices over the following weeks.

The update has already been released for Samsung’s newest smartphones

For a number of models, however, this version marks the finish line: they will receive the new interface, but there will be no further jump to a new Android version after this.

Full list of affected devices

Samsung has identified 19 models for which One UI 9.0 will be the last major update:

  • Galaxy S23
  • Galaxy S23+
  • Galaxy S23 Ultra
  • Galaxy S23 FE
  • Galaxy Z Fold 5
  • Galaxy Z Flip 5
  • Galaxy A54 5G
  • Galaxy A34 5G
  • Galaxy A24 4G
  • Galaxy M54 5G
  • Galaxy M34 5G
  • Galaxy F54 5G
  • Galaxy F34 5G
  • Galaxy Tab S9
  • Galaxy Tab S9+
  • Galaxy Tab S9 Ultra
  • Galaxy Tab S9 FE
  • Galaxy Tab S9 FE+
  • Galaxy Tab S6 Lite (2024)

It’s worth noting that these devices are far from obsolete. The Galaxy S23 series, for example, remains capable hardware with plenty of performance headroom for continued daily use.

Support won’t end overnight

It’s important to distinguish between the end of major OS updates and the end of all support. Receiving the last version of Android does not mean a device will stop getting any updates at all. Even after the final major upgrade, Samsung will continue to release security patches for at least another year, and for flagships the security update window is typically longer.

The S23 and other devices won’t stop receiving updates overnight

These security patches arrive on a regular monthly schedule. The devices on this list were still included in Samsung’s most recent round of security patches, demonstrating that support remains active.

There is also an additional possibility: some of these devices may receive One UI 9.5 in 2027. While this would not technically be a new OS — it would still run Android 17 under the hood — it could bring interface refinements and additional features.

Should you replace your device now?

If your phone or tablet appears on this list, there is no urgent reason to replace it. The device will remain functional, secure, and running a current interface for a considerable time to come. Nothing dramatic happens the moment a device receives its last major OS update.

Nothing catastrophic will happen — you simply won’t receive new OS features beyond this point

That said, buying any of these devices new at this stage is harder to recommend, since their major-update runway is now effectively over. Within a year or so, they will be at the very edge of Samsung’s support window. For anyone looking to purchase a Samsung device for long-term use, newer model lines would offer a longer update horizon.

For current owners of a Galaxy S23, Tab S9, or any other device on the list, the practical takeaway is straightforward: continue using your device without concern. It will remain well-supported for the foreseeable future.
