One UI 9 rollout timeline
Samsung has begun pushing its Android 17 based One UI 9 skin to a broad range of older Galaxy devices. The first wave arrived in South Korea, followed quickly by North America, Europe and India. The most recent additions include the full Samsung Galaxy S23 series, Samsung Galaxy S24 series, Samsung Galaxy Z Fold 5, Samsung Galaxy Z Flip 5, Samsung Galaxy Z Fold 6 and Samsung Galaxy Z Flip 6. In practice this means that every flagship Samsung Galaxy phone launched since the start of 2023 is now slated to receive the major software refresh.
Key features of One UI 9
One UI 9 focuses on deeper customisation and smarter AI assistance. The Quick Panel can now be rearranged with drag‑and‑drop tiles, letting users surface the shortcuts they use most. Samsung DeX receives performance tweaks and smoother multi‑window handling, making a phone feel more like a desktop when connected to an external display. Samsung Notes adds richer handwriting tools and tighter integration with the new AI summariser. A location privacy indicator alerts users when apps access their precise location, echoing trends in other Android 17 builds. Among the AI‑driven utilities, Call Brief analyses incoming calls in real time and displays a short description of the caller’s intent, while My FanCam locks focus on a moving subject in existing video and reframes the clip around that person.
What older flagships gain
Owners of the Samsung Galaxy S23 and Samsung Galaxy S24 will notice a fresher visual language and faster app launches thanks to the updated runtime. The Samsung Galaxy Z Fold 5 and Z Flip 5 gain smoother hinge animations and a more responsive multitasking experience, while the Samsung Galaxy Z Fold 6 and Z Flip 6 inherit the same DeX enhancements that were first showcased on the newer foldables. Even devices that debuted a year ago, such as the Samsung Galaxy S23 Ultra, now benefit from the AI‑powered battery optimiser that learns usage patterns and extends screen‑on time.
Comparison with other Android 17 devices
Samsung is not alone in navigating the quirks of Android 17. Google’s own Pixel 11 Pro is currently running a version of the OS that lags behind the more polished build found on the older Pixel 6, a situation that has drawn criticism from early adopters. Both manufacturers are working on stability patches, but Samsung’s staggered rollout appears to be progressing more smoothly after the initial delays.
Looking ahead
All eyes are now on the upcoming Samsung Galaxy S27 series, which is expected to launch with One UI 9 already baked in. The current update demonstrates that Samsung can extend major feature sets to devices that are already a year old, suggesting that future flagships will continue to receive substantial upgrades throughout their lifecycle. Users who have held onto a Samsung Galaxy S23 or Samsung Galaxy Z Fold 5 can expect their phones to feel almost brand new after the One UI 9 refresh.
