Samsung One UI 9 based on Android 17 has started rolling out, bringing new Galaxy AI tools, privacy features, camera upgrades and more to eligible Galaxy phones and tablets.
Samsung has officially started the One UI 9 rollout based on Android 17, bringing new Galaxy AI features and useful changes to supported devices. The stable update started on September 16 with the Galaxy S26, Galaxy S26+ and Galaxy S26 Ultra, after first debuting on the Galaxy Z Fold8 Ultra, Galaxy Z Fold8 and Galaxy Z Flip8. Samsung will expand the update to more Galaxy smartphones and tablets in phases.
Samsung began the official One UI 9 update rollout on September 16, 2026. The Galaxy S26 series is the first older-generation flagship family to receive the stable update, while the latest Z series already has One UI 9.
The expected eligible devices include:
The broader eligibility list is based on Samsung's update policy and available support information, rather than an official single-device list from Samsung.
One UI 9 focuses heavily on Galaxy AI, but several additions are designed around everyday phone use rather than just generating content.
Samsung is also making privacy and security a bigger part of the One UI 9 experience. Security Brief can surface alerts about malware, unknown-source apps and unnecessary permissions through Now Brief.
Privacy Alerts use on-device AI to identify possible privacy risks, including apps trying to access permissions in the background. Samsung is also expanding Scam Detection to more countries and languages for supported Galaxy devices.
Another practical addition is Warranty and Care, which puts warranty information, device diagnostics, repair estimates and Samsung Care+ options inside Settings. Availability of individual functions can vary by country and device.
Eligible users can check for the Android 17-based One UI 9 update manually by going to:
Settings then software update then download and install
The rollout is phased, so an eligible Galaxy phone may not receive the update immediately. Samsung also notes that features and availability can vary depending on the device, country, language and account.
