One UI 8: which Samsung devices are already testing

Samsung’s software team has been hard at work fine-tuning One UI 8 — the company’s Android 16-based interface — and testing builds on a wide range of Galaxy devices. What began as early beta trials for flagship models has quickly expanded to include mid-range phones, foldables and tablets, signalling a broad rollout path ahead.

The first public beta waves for One UI 8 started in May with the Galaxy S25 series. Since then, August saw Samsung pushing internal and beta builds to many additional models, accelerating device coverage well beyond flagship handsets. The testing now spans everything from family-focused A-series phones to the latest foldable hardware and the company’s tablet line-up.

What this means for owners and buyers

For current Galaxy owners, the broad spread of internal and beta builds is good news: it indicates Samsung is preparing One UI 8 for a wide swath of hardware — not just the newest flagships. If your device appears on the list, you may see public beta invitations in coming weeks or receive the final update sooner than devices not yet in testing.

Samsung’s developers still have several months of work ahead to stabilise Android 16-based One UI 8 across dozens of SKUs and regional variants. Internal testing, beta feedback and the usual compatibility checks for apps and enterprise features will determine the public rollout cadence. For now, users can expect an extended beta period followed by staged releases once Samsung signs off on stability and performance.
