Samsung's stable One UI 8.5 rollout began last week in South Korea, covering the S24 and S25 families, 2024-era foldables, and the Tab S10 and S11 series. The S23 generation and anything older is not on the confirmed stable release list. If headlines describing this as a rollout for “older Galaxy phones” left you checking your S22's software update screen, that's the correction this article exists to make.
The update itself is substantive. New AI tools, a repositioned Bixby, and a set of security additions give eligible owners something meaningful. The problem is the gap between Samsung's “expanding to more devices” framing and what the confirmed device list actually shows.
One UI 8.5 eligible devices: stable rollout vs. beta-only access
The Samsung Global Newsroom and Samsung US Newsroom confirmed the following devices for stable release last week:
| Category | Devices |
|---|---|
| S-series phones | Galaxy S25 Ultra, S25+, S25, S25 FE; Galaxy S24 Ultra, S24+, S24, S24 FE |
| Foldables | Galaxy Z Fold7, Galaxy Z Flip7, Galaxy Z Fold6, Galaxy Z Flip6 |
| Tablets | Galaxy Tab S11 Ultra, Tab S11; Galaxy Tab S10 Ultra, Tab S10+, Tab S10 Lite |
One UI 8.5 debuted with the Galaxy S25 series, the Galaxy Z Fold7, and the Galaxy Z Flip7, per the Samsung US Newsroom in late March. The stable rollout now extends that outward to the S24 generation and 2024-era foldables.
The Galaxy S23 series, Galaxy Z Fold5, Galaxy Z Flip5, Galaxy S23 FE, and Galaxy A36 5G received beta builds through April, according to the Samsung US Newsroom. The beta access came with hard geographic limits: the Z Fold5 and Z Flip5 beta ran only in Korea and the U.S.; the A36 5G beta was restricted to India. None are confirmed for stable release, and Samsung has not published a timeline for when, or whether, that changes.
Samsung's public commitment on regional timing beyond South Korea amounts to four words: “additional regions to follow,” per the Samsung Global Newsroom last week.
