By late 2026, Samsung is executing a global rollout of One UI 9, based on Android 17. Following initial deployment in South Korea and via carriers like T-Mobile in the United States, the update has expanded to include the Galaxy S26, S25, S24, and S23 series, as well as Galaxy Z Fold 8, Z Flip 8, Z Fold 7, Z Fold 6, and Z Flip 7. The rollout has reached international markets including Spain, Bulgaria, Germany, Italy, Brazil, India, and Greece. One UI 9 introduces advanced Galaxy AI tools, including ‘My FanCam’ for subject tracking, ‘Now Nudge’ for contextual suggestions, ‘Now Brief’ for personalized information cards, and ‘Call Brief’ for call summaries. Other features include a redesigned Bixby, improved document scanning, enhanced Samsung DeX tools, and improved privacy and security alerts, such as on-device AI-powered ‘Privacy Alerts’ and new indicators for location access. While basic AI features are currently free, Samsung has noted that future advanced services may require a subscription. Technical issues have emerged during the rollout. Users of the Galaxy S24 and S25 series have reported significant battery life degradation, with some reporting drops from 100% to 5% in five hours. Additionally, some Galaxy A57 users have reported critical errors where devices become stuck on an XML error screen during setup. ~~While experts suggest~~ Users of the Galaxy S26 Ultra have also reported critical stability issues, including an infinite boot loop during initial setup and a ‘web page not available’ error on a black screen.
