Samsung has released the first beta version of One UI 9 for its Galaxy S26 series smartphones. The update, designated as Beta 1, arrived in Germany and the United States on May 5, 2026. This release marks the first time Samsung has provided a beta build based on Android 17.
Initial rollout prioritizes Galaxy S26 Ultra over standard models
The software update requires a download size of 3.6 GB. It includes security patches dated May 5, 2026. Key feature improvements include enhanced desktop previews for Samsung DeX. The update also introduces additional customization options for the Quick Panel, which were absent in the previous One UI 8 release.

Initial rollout observations suggest that the Galaxy S26 Ultra receives priority access over the standard Galaxy S26 and Galaxy S26 Plus models. This prioritization appears to be based on user reports from Reddit rather than official confirmation from Samsung. The company has not yet clarified the specific rollout schedule for other regions or device variants.
One UI 9 Beta 1 represents a significant software milestone for the Galaxy S26 lineup. It establishes the foundation for the next generation of Samsung's mobile operating system. The early availability in select markets allows developers and enthusiasts to test compatibility with Android 17 features.
