So, whenever Samsung starts testing One UI 9 on a new Galaxy device, launches a public beta, or begins rolling out the stable update, you’ll find the latest development here first.

Which Galaxy phones are expected to receive One UI 9?
Samsung hasn’t published the official rollout schedule yet. However, based on Samsung’s update policy and internal testing, these categories are expected to receive One UI 9 later this year:
- Galaxy S Series
- Galaxy Z Fold Series
- Galaxy Z Flip Series
- Galaxy Tab S tablets
- Galaxy A Series (selected models)
- Galaxy M Series (selected models)
- Galaxy F Series (selected markets)
- Galaxy XCover devices
Not every eligible device will receive a beta program. In fact, Samsung traditionally limits beta testing to flagship models and a handful of premium devices. Most Galaxy A-series phones, tablets and entry-level devices will simply receive the stable update when it’s ready.
When will Samsung release the stable One UI 9 update?
Samsung is expected to publicly debut the stable version of One UI 9 alongside the Galaxy Z Fold 8 and Galaxy Z Flip 8 before gradually expanding the rollout to older eligible Galaxy phones and tablets. Once that happens, the rollout will likely follow Samsung’s usual order:
- Galaxy S26 Series
- Galaxy S25 Series
- Galaxy Z Fold 7 & Galaxy Z Flip 7
- Galaxy S24 Series
- Older flagship Galaxy S devices
- Galaxy tablets
- Galaxy A Series
- Entry-level Galaxy devices
Samsung usually prioritizes flagship devices before gradually expanding the rollout to mid-range and budget phones over the following months.
