Samsung has begun rolling out One UI 9 Beta 3 to enrolled Galaxy S26 devices in a handful of markets. The 1.7 GB update arrives as version S94x BXXU3ZZF7 and bundles the June 2026 security patch. Testers in South Korea, the United Kingdom, Poland and India can already download it, while other regions await deployment.

The changelog focuses on stability fixes: a reboot that triggered during video streaming is resolved, as is a white‑screen glitch when taking calls. Samsung also patches a black background issue in the status‑bar pull‑down, restores full file listings in the Files app, and refines 30× camera zoom focus. Minor UI quirks such as home‑screen swipe and lock‑screen widget updates are addressed.

With Beta 3 released just weeks after Beta 2, Samsung signals a tight development schedule ahead of the expected One UI 9 public launch at the July Unpacked event. The rapid iteration aims to iron out bugs before wider rollout, meaning early adopters will see a more polished experience while the broader user base waits for the final version.

Consumers enrolled in the beta program can opt out at any time via Settings, ensuring they retain a stable OS while Samsung finalizes the feature set. The opt‑out process restores the stable release build and preserves data, a safeguard for users wary of frequent beta changes. Samsung advises feedback through its Galaxy Members app to prioritize remaining issues before the full One UI 9 rollout.
