Breaking: One UI 9 Beta Builds Appear for Galaxy S26 Series
Samsung's internal testing for One UI 9 has reportedly begun for the Galaxy S26 series. Tipsters spotted the first beta builds on Samsung's servers, suggesting the company is preparing for a public release.
The beta builds, numbered ZZE7 and BZE7, correspond to the Galaxy S26 Plus and Galaxy S26 Ultra. This marks the earliest known sign of One UI 9 development outside Samsung's labs.

"Seeing beta firmware appear on Samsung's servers is a classic signal that internal testing has started," said Lee Joon-ho, a mobile software analyst at Seoul-based TechInsights. "It typically means a public beta launch is weeks to a couple of months away."
Tipsters Kailash and Tarun Vats first flagged the builds on X, with SammyFans confirming the details. The builds are not yet available for download, but their existence confirms Samsung is actively iterating on the next One UI version.
Background: One UI 8.5 and the Wait for Older Devices
The Galaxy S26 series launched with One UI 8.5 based on Android 15. However, many older Galaxy devices are still waiting for the One UI 8.5 update to roll out.
Samsung typically releases major One UI betas for its newest flagships first. The S26 series is now the testbed for One UI 9, which is expected to bring enhanced AI features and a redesigned notification panel.
What This Means for Users
For Galaxy S26 owners, the appearance of these builds suggests they could be among the first to try One UI 9. Public beta access may open in the coming weeks, assuming no major bugs are found during internal testing.
Owners of older Galaxy devices, such as the S25 or S24 series, will likely have to wait several months after the S26 beta matures. Samsung usually extends beta programs to previous-gen phones once the new flagship's beta is stable.
What This Means: Your Questions Answered
Timeline: Based on previous patterns, a public beta for the Galaxy S26 series could launch within 4–6 weeks. Samsung's One UI 6 beta for the S23 series appeared on servers about two months before public release.
Features: One UI 9 is rumored to include deeper AI integration, improved multitasking, and a refreshed lock screen. However, Samsung hasn't officially confirmed any changes yet.
Who gets it first: Galaxy S26 Plus and Ultra seem to be the initial targets. The base S26 model may follow shortly after.
Should you install the beta? If you own a Galaxy S26 and are comfortable with potential instability, signing up for the beta can give you early access. Otherwise, wait for the stable release later this year.
