Samsung’s One UI 9 update, built on Android 17, reached carrier-branded versions of last year’s Galaxy phones in the United States this week. According to a report published October 5, 2026, the Galaxy Z Fold 7 is receiving it on T-Mobile and Verizon, the Galaxy Z Flip 7 on AT&T, and the Galaxy S25, S25 FE and S25 Edge on Verizon.
The rollout is staggered by model and by carrier, and unlocked versions of the same phones had not yet been updated when the report ran.
Carrier-by-Carrier Model List
9to5Google’s October 5 report is the report that lists the older-device wave. It describes Samsung expanding its Android 17 (One UI 9) distribution beyond the Galaxy S26 series to additional devices in the United States, and notes that Samsung had delayed the rollout before beginning broader distribution at the end of September. The model list reads as follows: the Galaxy Z Fold 7 on T-Mobile and Verizon, the Galaxy Z Flip 7 on AT&T, and the Galaxy S25 series on Verizon, specifically the S25, S25 FE and S25 Edge. Unlocked variants are expected within days.
Six models are named in all once the S26 line, which started the rollout, is counted: the Galaxy Z Fold 7, Galaxy Z Flip 7, Galaxy S25, Galaxy S25 FE, Galaxy S25 Edge and Galaxy S26. It is also narrower than a blanket claim about every S25 on every network would be. In the report, the S25 family appears on one network, Verizon, while the Fold 7 appears on two. AT&T’s only named device in the report is the Flip 7.
The report gives update-checking instructions as well: Settings, then Software update, then Download and install. It also cautions that availability varies by carrier and by model, and that some carriers receive the update before others, so a phone that is eligible on paper may not see a prompt on the day another owner’s does, and a carrier-locked Fold 7 on one network can be updated while the same model on another waits.
September Delay and the Galaxy S26 Head Start
The older phones are the second wave, and the first wave was bumpy. Android Central reported on September 23 that One UI 9 had reached only T-Mobile’s Galaxy S26 Ultra in the U.S., with unlocked phones and those on AT&T and Verizon still waiting. Samsung had originally announced a September rollout expected around September 21, and reports had pointed to a possible indefinite delay before the T-Mobile units appeared, an early release the outlet suggested might have jumped the gun.
By September 28, the picture widened. Android Authority reported official firmware listings for the S26, S26 Plus and S26 Ultra on T-Mobile, Metro by T-Mobile and U.S. Cellular, with unlocked models starting to receive it. The build it cited carried a September 5, 2026 security patch.
The same day, Droid Life found that unlocked S26 models and Google Fi were receiving the update while locked AT&T and Verizon units did not appear to be live yet. Droid Life described this as a broader expansion following a targeted T-Mobile rollout the previous week. It put the download at about 4GB for phones that were not in the beta program, and around 600MB or more for former beta testers.
Samsung’s own announcement of the start came earlier and from abroad. Samsung Newsroom India said the official rollout began September 16, 2026, with the Galaxy S26, S26+ and S26 Ultra. That release does not name an Android version number, so the Android 17 label in U.S. coverage comes from the outlets reporting on the update.
Regional Dates That Do Not Translate to the U.S.
One date that circulated for the older phones belongs to another country. Android Authority reported on September 17 that Samsung Thailand had announced the Galaxy S25 series, Galaxy Z Fold 7 and Galaxy Z Flip 7 would start receiving the Android 17-based update on September 28, with the Galaxy S23 FE following in October.
The outlet itself cautioned that those dates come from Samsung Thailand and may not represent a global schedule, and that timing will vary by country and carrier. It added that Samsung’s U.S. announcement had confirmed only the Galaxy S26 rollout, without detailing older-device timing. The October 5 U.S. report is therefore the first sourced record located that places the Fold 7, Flip 7 and S25 models on named American carriers.
The features Samsung has publicly attached to One UI 9 include FanCam, a video feature that auto-tracks and centers selected people, Now Nudge, which offers context-aware suggestions during tasks, and a Thread View in Interpreter for translated conversations, per Samsung Newsroom India. Android Authority’s changelog adds a redesigned Samsung Health and a quick-lock feature. Which of those arrive on each older model, and when, is not specified in the U.S. report.
