Samsung’s One UI journey kicked off in November 2018 with version 1.0. It completely replaced the older TouchWiz interface, which was notorious for its laggy and sluggish performance. Since that first release, Samsung has pushed out major updates roughly every six months. It has released 19 major One UI updates to date. Here is a detailed list of all One UI versions with their release dates, Android versions, and key features of each update.
Samsung’s One UI release schedule shows a clear pattern. Beta versions typically arrive about two months before stable releases. The final versions usually roll out during the last quarter of each year. However, One UI 7.0 broke this pattern. It was originally expected in late 2024, but Samsung postponed it to April 2025 to focus on what they called “one of the biggest updates in the history of One UI.”

Samsung’s One UI Update Strategy
While most OEMs rush updates to devices immediately after internal testing, Samsung takes a different approach. If you look at the pattern across previous releases, you’ll spot Samsung’s One UI update strategy. The Korean tech giant prefers a phased rollout that prioritizes stability over half-baked software. Instead of chasing deadlines, it focuses on delivering final updates, even if that means waiting a bit longer.
First, Samsung launches a beta program for users willing to test the early software. The beta program typically runs for 2-3 months, which helps the company iron out the reported bugs. When the final version rolls out, the S-series devices get the first dibs, followed by the Flip/Fold devices, and then it makes its way to the mid-range and budget models. Major updates typically arrive between October and December, and minor updates (.1 versions) roll out around January-February.
