One UI 9 Reaches the Galaxy S25 and Z7 Foldables
Samsung Thailand's schedule puts the Galaxy S25 series and the Galaxy Z Fold7 and Z Flip7 on One UI 9 from 28 September 2026, alongside the Galaxy S26, which it moved to the same day. Samsung's global announcement gave no date for older phones.
- Samsung Thailand's newsroom roadmap sets 28 September 2026 as the start of the One UI 9 rollout for the Galaxy S25 series and the Galaxy Z Fold7 and Z Flip7[1][3][4]
- The Galaxy S25 line covered includes the S25, S25+, S25 Ultra, S25 Edge and S25 FE[1]
- This follows the stable One UI 9 debut in South Korea on 16 September 2026 with the Galaxy S26, S26+ and S26 Ultra, after the software first shipped on the Galaxy Z Fold8 Ultra, Fold8 and Flip8 and out of the box on the Galaxy S26 FE[1][3][5]
- Samsung's global press release gave no rollout dates for older phones, only noting the models that would receive the Privacy Alerts feature, which makes the Thai posting the clearest official indication of plans beyond the S26 series[1][4][5]
- Samsung Thailand originally listed 21 September for the Galaxy S26 series, then moved that date to 28 September so the S26 lines up with the S25 and Z7 foldables - a week's extra wait[2][3]
- Sammy Fans reported on 22 September 2026 that the Thai page later dropped a fixed date altogether in favour of "Within September", which the site framed as a change to the announcement timing rather than a confirmed delay of the update itself[2]
- Older devices remain unscheduled: the press release said One UI 9 would reach the Galaxy S23 FE "by October", later softened by Samsung to later this year, while the Galaxy S24 and S23 series go unmentioned[1][2][4]
- Both SamMobile and Android Authority caution the dates may apply only to Thailand and could be tentative, with exact timing varying by country and carrier; Samsung's US announcement covered only the 16 September S26 start and Canada's cited 21 September[3][4]
- The Galaxy S22 series has already had its final major update (Android 16 / One UI 8) but continues to get quarterly security patches[1]
- In the event's wake, Samsung began the global stable rollout for the Galaxy S26 series in the US on 23 September 2026, prioritising Beta 7 participants, and said it plans to upgrade all eligible devices by the end of the year[2]
Notable features
- One UI 9 is Samsung's Android 17-based interface release, tested through a beta programme running since May 2026 with seven major beta builds for the Galaxy S26 series, and positioned as the foundation for a later One UI 9.5 upgrade[2][3][4]
- My FanCam automatically tracks a chosen person in a recorded video and keeps them centred, reframing the footage as the scene moves; it requires a Samsung Account and is not supported when there is no subject to track[2][5]
- Now Brief gains Generative and Editable Cards so users can build their own daily-summary cards across health, weather and video[5]
- Now Nudge surfaces context-aware suggestions in the flow of use, such as pulling up reservation details or saving a shared location from a conversation, working with Samsung Messages, Google Messages and Google Chat[2][5]
- Creative Studio suggests image-generation prompts tied to upcoming events such as a friend's birthday[2][5]
- Interpreter adds a Thread View for reviewing earlier exchanges, with faster Conversation Mode translation and quicker playback on compatible Galaxy Buds[5]
- Document Scan handles curved book pages and folded corners with less manual correction, adds large-screen-optimised views and an improved Finger Eraser; Voice Recorder structures summaries with headings and tables[2][5]
- Security and privacy additions: a Security Brief inside Now Brief flagging malware, unknown-source apps and unnecessary permissions; on-device AI Privacy Alerts; and Scam Detection expanding to Japan, Canada and India[2][5]
- Privacy Alerts support spans the Galaxy S26/S25/S24/S23 families (including FE models), Z Fold8 Ultra/Fold8/Flip8 down to Fold5/Flip5, and Tab S11, S10 and S9 tablets[5]
- Warranty and Care moves device support into Settings, covering warranty checks across linked devices, self-diagnostics, repair estimates and Samsung Care+ management or service booking, with availability varying by region[2][5]
