Samsung has started expanding One UI 9 beyond its latest foldable phones, with the Galaxy S26, Galaxy S26+ and Galaxy S26 Ultra receiving the update from September 17. The software previously debuted on the Galaxy Z Fold8 Ultra, Z Fold8 and Z Flip8, and Samsung says availability will gradually extend to additional Galaxy devices.
One UI 9 continues Samsung’s push to make Galaxy AI less of a standalone collection of tools and more of something embedded throughout everyday phone use. One of the more interesting additions is My FanCam, which can track a selected person in an existing video and automatically reframe the footage to keep them centred. It could prove useful for concerts, sports and family videos, although Samsung notes that tracking accuracy is not guaranteed.
Now Brief is also becoming more customisable. Users can create and edit cards covering areas such as health, weather and video, giving them greater control over what appears in Samsung’s daily information summaries. A new Now Nudge feature takes a more proactive approach, surfacing contextual actions such as recalling reservation information or saving locations mentioned during conversations.

Samsung is also bringing device support deeper into One UI. A Warranty and Care section inside Settings can display coverage for connected devices, run diagnostics, provide repair estimates in supported markets and offer access to Samsung Care+ and official support services.
Several existing tools receive smaller but potentially useful improvements. Interpreter gains a Thread View for reviewing earlier parts of translated conversations, alongside faster Conversation Mode translations and reduced playback delays with compatible Galaxy Buds. Document Scan is designed to better handle awkward material including curved book pages and folded corners, while Voice Recorder summaries can now use headings and tables to make longer recordings easier to digest.
Security receives similar attention. Security Brief can surface warnings about malware, unknown-source apps and unnecessary permissions through Now Brief. Enhanced Privacy Alerts use on-device AI to identify potentially unnecessary background permission requests, although Samsung cautions that the system may not identify every relevant privacy issue.
Scam Detection is also expanding to Japan, Canada and India, extending Samsung’s attempt to identify potentially fraudulent calls across more markets and languages.
The bigger story with One UI 9 is therefore not any single headline feature, but Samsung’s continued shift toward proactive software that anticipates what users might want next. That can make Galaxy devices more convenient, but it also makes transparency and user control increasingly important as AI becomes more deeply woven into routine interactions.
