Samsung began the rollout of One UI 8 stable update earlier this week, but it has been working on One UI 8.5 for the Galaxy S26 series for the past few months. A One UI 8.5 firmware for the Galaxy S25 Ultra was also spotted on Samsung’s server recently, and now we hear that a leaked One UI 8.5 firmware that’s been making rounds online contains code that confirms One UI 9.0 will be the next major version of One UI.

While One UI 8 and the under-development One UI 8.5 are based on Android 16, One UI 9.0 will likely be based on Android 17. And we know that it’s too early to say anything about One UI 9.0’s rollout with certainty, chances are it will debut with next year’s Galaxy Z Fold and Galaxy Z Flip folding smartphones.

While we await more details about One UI 9.0, you can head this way for the official One UI 8 stable update rollout schedule shared by Samsung. But note that it doesn’t apply to all regions.
