One UI replaced Samsung Experience at the turn of 2019, first as the Android 9 update for the Galaxy S9 and Note9, then preinstalled on the Galaxy S10. Since then every major number has meant one Android major: One UI 2 is Android 10, One UI 6 is Android 14, and so on. That makes the Android version in a firmware the reliable way to tell which One UI it carries.
Point releases are a Samsung habit: the next flagship launches with an x.1 or x.5 on the same Android, and older models get it a few months later. One UI 2.5 came with the Galaxy Note20, 3.1 with the S21, 4.1 with the S22, 5.1 with the S23 and 6.1 with the S24. Because they share the Android version, this page counts them under their major: One UI 8.0 and 8.5 are all on the One UI 8 page.
Release order is predictable. A new major starts with the year's foldables or the S series, reaches the previous flagships within weeks, then the A5x and A3x mid-range, and the budget A0x and A1x phones last. Tablets usually trail phones of the same class. One UI 7 broke the pattern: the Galaxy S25 shipped with it in February 2025, but the S24 only got the stable release in April.
Open Settings, About phone, Software information. The first line is the One UI version, below it the Android version and the build number. The build number tells you more than the version alone: the guide to checking Samsung firmware versions explains how to read it and how to see whether a newer build exists for your model and region.
For tablets the same list is on the Galaxy Tab software update page, sorted by the latest build of each model.
The latest One UI is One UI 9, based on Android 17. 341 Galaxy models have firmware with it in our archive, the first build was for Galaxy Z Flip8 (SM-F7760) on 2026-06-25.
Each One UI major matches one Android major: One UI 9 is Android 17, One UI 8 is Android 16, One UI 7 is Android 15, One UI 6 is Android 14. Point releases such as 6.1 or 8.5 keep the Android version of their major.
Open the One UI 9 page: it lists every model that already has a build and the models Samsung guarantees the update for that are still waiting.
Go to Settings, Software update, Download and install. If the update has not reached your region yet, you can install the official firmware yourself for your exact model with Odin; a full install with the CSC file wipes the phone, HOME_CSC keeps the data.
A lighter edition of One UI on budget Galaxy A and M phones. It has the same version number and Android base but leaves out some features, such as Secure Folder or Samsung DeX, depending on the model.
Based on the Android version Samsung's firmware server reports for each build in our archive. Beta builds are not included.
