GoKawiilSamsung confirms stable One UI 9 rollout for Galaxy S26 on more US carriers
Samsung's support pages now list stable One UI 9 builds for the Galaxy S26, S26 Plus, and S26 Ultra on T-Mobile, Metro by T-Mobile, and US Cellular, carrying build S94xUSQU4BZID with a September 5, 2026 security patch. Unlocked Galaxy S26 Ultra units are also beginning to receive the update via a smaller download, and Samsung has published a full changelog covering Galaxy AI, Samsung Health, privacy, Bixby, accessibility, and DeX features.
GoKawiil's interpretation of the reporting above, not reported fact.
The staggered carrier-by-carrier rollout suggests Samsung is still finalizing distribution rather than pushing a simultaneous global release, which could mean AT&T, Verizon, and broader unlocked users wait longer. The small update size for some unlocked devices indicates many testers who ran the One UI 9 beta will get a lighter final patch rather than a full upgrade, hinting at how Samsung manages beta-to-stable transitions.
- Stable One UI 9 is now officially listed for Galaxy S26 series on T-Mobile, Metro by T-Mobile, and US Cellular.
- Unlocked Galaxy S26 Ultra devices are beginning to receive a smaller update, suggesting beta testers are transitioning to stable.
- AT&T, Verizon, and broader unlocked rollout have not yet been officially confirmed by Samsung.
