Samsung unveiled One UI 8.5 for supported Galaxy devices after five months of beta testing

Samsung has officially released One UI 8.5

The company announced the release of a stable version of its flagship interface—One UI 8.5—which is now available for most Galaxy smartphones and tablets.

Key facts
When on devices First beta version of One UI 8.58 December 2025 – Appearance in the Galaxy S26 series End of February 2026 – Expanded testing to Z Fold 7 and others Mid-March 2026 – Official release May 13 2026 (current date) Galaxy S25, S24, Z Fold 7/6, Z Flip 7/6, Tab S11, Tab S10 and their variants

Why it matters
* Long testing period—over five months, which is unusual for Samsung. The core Android system (version 16) remained unchanged, and the update affected only the interface.

* New features and design—One UI 8.5 includes significant user‑interface improvements and new capabilities that make it more than just a cosmetic upgrade.

* Comparison to the past—a similar delay occurred with the release of One UI 7 in 2025, but in recent years Samsung has typically updated its devices quickly. These cases have become notable exceptions.

How to get the update
Samsung is already distributing the stable version worldwide. Currently available for:

* Galaxy S25 (S25, S25+, S25 Ultra, S25 Edge, S25 FE)

* Galaxy S24 (S24, S24+, S24 Ultra, S24 FE)

* Galaxy Z TriFold, Z Fold 7, Z Fold 6

* Galaxy Z Flip 7, Z Flip 7 FE, Z Flip 6

* Galaxy Tab S11 and Tab S10

The list will soon expand, so owners of other Galaxy models will not be left without an update.

Thus, One UI 8.5 represents a significant step forward in the user experience on Samsung devices, and the long testing cycle underscores a focus on quality and stability of the new interface.
