Samsung One UI 9 is the latest major version of Samsung’s smartphone software, bringing improvements to Galaxy AI, personalization, accessibility, security and everyday usability. Built on Android 17, Samsung One UI 9 aims to make compatible Galaxy phones and tablets more helpful, intuitive and secure.
Samsung has officially announced the rollout of One UI 9, initially introducing the software on its latest Galaxy Z series before expanding availability to the Galaxy S26 series and other supported devices. However, the availability of individual features and the update itself can vary by model, country and carrier.
In this guide, we explain the most important One UI 9 changes, supported-device information, installation steps and what Galaxy users should know before updating.
What Is Samsung One UI 9?
One UI 9 is Samsung’s customized Android interface for compatible Galaxy devices. It builds on Android 17 while adding Samsung’s own interface design, Galaxy AI features, accessibility options, privacy tools and system applications.
Unlike a standalone application, One UI is deeply integrated into the phone’s operating system. It influences the Settings menu, notifications, Quick Panel, Samsung Notes, camera-related experiences and other everyday functions.
The main goal of One UI 9 is to reduce the effort required to complete common tasks while giving users greater control over their devices.
What’s New in Samsung One UI 9?
One UI 9 introduces several improvements across productivity, photography, personalization and device protection.
1. Enhanced Galaxy AI
Samsung has expanded AI-powered assistance with features such as Now Nudge, which can suggest relevant actions based on supported contexts. For example, when making plans through a compatible messaging app, a user may receive suggestions to access reservation details or save a shared location.
2. My FanCam
My FanCam can automatically track a selected person in a recorded video and reframe the footage to keep that person centered. This can be useful when recording performances, family occasions or sporting events.
3. More Personalized Now Brief
Now Brief introduces generative and editable cards that let users customize aspects of their daily summaries. Depending on device and regional availability, cards can cover information such as health, weather and video.
4. Improved Document Scanning
The updated Document Scan experience is designed to handle challenging pages, including curved book pages and papers with folded corners, with less manual adjustment.
5. Better Privacy and Security Information
Security Brief and Privacy Alerts help users understand potential security or privacy concerns. These tools can highlight issues such as suspicious applications, unnecessary permissions or potential privacy risks.
Feature availability is not identical across every Galaxy device.
Samsung One UI 9 Release and Rollout
Samsung began the public rollout expansion in September 2026, following the software’s debut on Galaxy Z Fold8 Ultra, Galaxy Z Fold8 and Galaxy Z Flip8. The Galaxy S26, S26+ and S26 Ultra were among the next devices included in the rollout.
Samsung is expanding availability progressively, so the announcement of a rollout does not mean that every compatible phone receives the update on the same day.
For current announcements, check the official Samsung Newsroom and your device’s Software Update settings.
Which Samsung Phones Will Get One UI 9?
Eligibility depends on the device model, its software-support commitment, regional firmware and Samsung’s rollout schedule. Do not assume that every Galaxy phone running One UI 8 will automatically receive One UI 9.
To check your device, open Settings, select Software update and tap Download and install. You can also consult Samsung’s official announcements for confirmed availability.
