Samsung One UI 9 update list and November 2026 rollout schedule

While preparing One UI 9.5, Samsung also updated its November 2026 schedule for Android 17-based One UI 9 and security updates.

In addition, Samsung has largely completed the stable One UI 9 rollout for its high-end phones. The process, which began with the Galaxy S26 series in mid-September, extended to the Galaxy S23 family by the end of October, expanding the list with many models. Has your phone received One UI 9, and which models got the update? Here is the release schedule and everything you need to know.

Which models did the One UI 9 rollout cover?

The main Samsung models that received the stable One UI 9 update during September and October 2026 and their rollout dates are as follows:

• September 16, 2026: Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra (US build numbers S942USQU4BZID, S947USQU4BZID, and S948USQU4BZID).
• September 28, 2026: The Galaxy S25 series began rolling out in South Korea before expanding to the global market.

• October 20, 2026: The Galaxy S24 series moved to One UI 9 in the US.
• October 23, 2026: Galaxy Z Fold 5, Galaxy Z Flip 5, as well as the Galaxy S23, S23+, and S23 Ultra received the update.

How do monthly, quarterly, and 7-year support work?

For a long time, Samsung offered 4 years of operating system updates and 5 years of security updates for its flagship phones. With the Galaxy S24 series and Galaxy Z Fold 6, this period increased to 7 years for both operating system and security patches. Models released before these devices remain limited to 5 years of support.

Flagship Galaxy S and Galaxy Z Fold series phones receive monthly security patches for most of their support period. When devices enter the final year of their support lifecycle, they drop to a quarterly update schedule. Tablets are updated on a quarterly schedule from the first day they are released.

Over the past year, many older models changed places on the schedule due to these rules. In February 2026, the Galaxy S22 series was moved to the quarterly list for its final year, while the Galaxy S21 series was removed from the list. In September 2026, the Galaxy Z Fold 4 and Z Flip 4 were moved to the quarterly schedule, and the Galaxy Z Fold 3, Z Flip 3, Galaxy Watch 4, and Watch 4 Classic, which completed their 5-year period, were completely removed from the list.

Support periods have also been extended for smartwatches. Galaxy Watch models, which are on a quarterly schedule from launch, began receiving 5 years of operating system updates and 5 years of security updates starting with the Galaxy Watch 9 and Galaxy Watch Ultra 2. Previous watch models were limited to 4 years of operating system updates and 5 years of security updates.

To check if there is an update on your phone, open the Settings app, go to "Software update," and tap "Download and install." On Galaxy Watch models, you can follow "Software update" in the Settings menu on your watch or use the path "Watch settings > Watch software update" in the Galaxy Wearable app on your phone.
