One UI 9 Official Rollout Begins — When Will My Galaxy Get It?

Samsung Electronics began rolling out the official version of One UI 9 in Korea on September 16, 2026. The first devices are the three Galaxy S26 models, S26, S26+, and S26 Ultra, with other models to follow in stages.

The version that launched first in July with the Galaxy Z Fold8 Ultra, Fold8, and Flip8 is now reaching existing users, but rollout timing by device differs between the official announcement and regional notices, and the new features come with conditions.

One UI 9 is based on Android 17, and development was made public on May 12, 2026 with a beta program for the Galaxy S26 series. The beta ran in Korea as well as the US, UK, Poland, Germany, and India, and the first devices to ship with the official version were the Galaxy Z Fold8 Ultra, Fold8, and Flip8, released on July 22.

The expansion to existing models came on September 16. In a release that day, Samsung Newsroom said it would start with the Galaxy S26, S26+, and S26 Ultra, and 9to5Google noted the schedule followed about four months of beta. The previous version, One UI 8.5, rolled out officially on May 6, so the gap between the two versions is a little over four months.

Schedules for older models vary by region. According to the schedule Samsung Thailand posted, the Galaxy S25 series and Z Fold7 and Flip7 get it on September 28 and the Galaxy S23 FE in October, but Android Authority added that these dates are for Thailand and may vary by country and carrier.

When	Devices	Status
July 22	3 Z Fold8 models	First to ship with it
September 16	S26, S26+, S26 Ultra	Korean rollout begins
September 28	S25, Z Fold7, Flip7	Per Thailand notice
October	S23 FE	Per Thailand notice
TBD	S24, S23, Tab S9 and later	Staged expansion

Supported devices

Samsung Electronics hasn’t published the full support list in one place. However, the footnote on supported devices for Privacy Alerts in the announcement effectively serves as the list, naming the Galaxy S26, S26 Ultra, S25, S25 FE, S24, S24 FE, S23, S23 FE; Z Fold8 Ultra, Fold8, Flip8, Fold7, Flip7, Fold6, Flip6, Fold5, Flip5; and Tab S11 Ultra, Tab S11, Tab S10 Ultra, Tab S10+, Tab S9 Ultra, Tab S9+, and Tab S9.

Line	Support baseline
Galaxy S	S23, S23 FE and later
Foldables	Z Fold5, Flip5 and later
Tablets	Tab S9 and later

SamMobile counted more than 93 eligible models, including the Galaxy A, Tab, F, M, and XCover lines. Conversely, the Galaxy S22 series, S21 FE, Z Fold4, and older A series are reported to be excluded, but this comes from overseas media tallies rather than official Samsung documents, so for Korean models it’s more accurate to check directly in the Software update menu.

New features

The headline feature of this version is My Fancam. It automatically tracks a chosen person in a video you shot and keeps them centered, reframing as the scene moves. It’s for tidying up video without editing when you want to keep just one person, such as a child’s performance or concert footage.

Now Brief adds generative and editable cards. You build cards yourself from health, weather, and video items, so you decide what shows up in your daily summary.

Now Nudge understands context and suggests the next action; if you’re setting up a meeting by message, you can pull up booking details or save a shared location without leaving the conversation.

Warranty & Care adds device support items to the Settings menu. Checking warranty coverage for devices linked to your Samsung account, running self-diagnostics, looking up repair estimates, managing Samsung Care+, and booking service are all handled inside Settings.

The rest are improvements to existing Galaxy AI features.

Creative Studio: proactively suggests image generation ideas based on upcoming events
Interpreter: thread view to check earlier conversation, conversation-mode translation, and shorter playback delay on Galaxy Buds
Document Scan: corrects curved book pages and paper with folded corners, improved finger removal
Voice Recorder: outputs summaries with headings and tables in an easy-to-skim structure

Security and privacy

There are three security changes. Security Brief gathers issues such as malicious apps, apps of unclear origin, and unnecessary permission use inside Now Brief and shows them periodically.

Privacy Alerts uses on-device AI to identify risk signals. When an app tries to access permissions unnecessarily in the background, it alerts you to the attempt, and since the judgment happens on the device, permission usage history isn’t sent to a server.

Scam Detection expands to more countries. The countries Samsung listed in a footnote are Japan, Canada, and India, so Korea isn’t directly part of this expansion, but voice-phishing suspected-call alerts have already been on by default since One UI 8.0, with a usage rate of about 84% as of April 2026.

Korean security features were also strengthened. In June 2026, Samsung said One UI 9 would not only block installation of phishing apps but also block apps already installed from running, based on data from cooperation with the Korean National Police Agency and Galaxy Store reputation data. Malicious message blocking run with the Korea Communications Commission and the Korea Internet & Security Agency has blocked about 400 million messages from its introduction in September 2024 through April 2026.

What Android 17 brings

Android 17, the foundation of One UI 9, brings platform-level changes separate from Samsung’s features.

System contact picker: instead of an app requesting permission to read all contacts, it specifies only the fields it needs and receives only the contacts the user picks (API level 37 and above)
Advanced Protection Mode: a mode that restricts certain features to reduce the attack surface, similar in nature to iOS Lockdown Mode
Direct satellite connectivity: improved support for satellite connections where there’s no cellular network
UWB ranging: adds the Downlink-TDoA API, which calculates position from signal arrival times at multiple anchors
Screen size adaptation: improves how apps adapt on devices with different screen sizes

Of these, the contact picker and Advanced Protection Mode only take effect when apps support them, so how much you actually notice depends on how fast apps update.

What to check before updating

Each feature has conditions. Just gathering the prerequisites Samsung listed in the announcement’s footnotes gives the following.

Feature	Prerequisite
My Fancam	Samsung account sign-in, not supported without a tracking target
Now Brief, Now Nudge	Samsung account, varies by country, language, and model
Interpreter	Language pack download required
Warranty & Care	Repair estimates vary by model and region
Scam Detection	Japan, Canada, India first

The scale of noticeable change should also be factored in. SamMobile said users coming from One UI 8.5 will hardly feel a big difference, and that this version focuses on refinement, so a major overhaul may come with One UI 9.5 launching alongside the Galaxy S27. The UI changes actually confirmed are about a waveform animation in the lock screen media player, the thickness of the brightness and volume sliders, and media controls that became circular.

Since it’s early in the rollout, stability reports are coming in. Posts on the Korean Samsung Members board say battery drain increased after the update, PiP video playback stutters, and the charging animation intermittently doesn’t appear.

On the other hand, there are also reports that control panel frame drops disappeared, so reactions seem to vary by device and usage pattern, but even for an official release it’s safer to keep in mind that it’s an early build.
