Overview
- Samsung has started delivering the stable One UI 9 build based on Android 17 to the Galaxy S26 series in a staged rollout that begins in the company’s home market and will expand to other regions.
- Parallel beta activity is expanding features to older devices: One UI 9 Beta 2 for the Galaxy S24 adds Call Brief, My FanCam, customizable Now Brief cards, and Now Nudge from the S26 and Z8 lineups.
- The Z Fold 6 and Z Flip 6 have also received a second One UI 9 beta that brings bug fixes, stability improvements, and additional Galaxy AI features in a rollout that began in South Korea.
- Some advanced AI functions depend on hardware and memory limits, with deeper Gemini-driven capabilities generally restricted to devices with roughly 12GB of RAM or compatible chipsets, so not all phones will get full functionality.
- Outlets and Samsung advise caution for beta installs, urging users to back up data and avoid putting beta builds on daily drivers while Samsung continues iterative fixes and wider staged distribution.
