Samsung Accelerates One UI 9 Beta Testing Across Four Flagship Generations and New Foldables

In early July 2026 Samsung confirmed that internal testing of its upcoming One UI 9 has begun on a broad set of devices, ranging from the Galaxy S23 FE and M34 to the Z Fold 6, Z Flip 6 and a newly spotted A37 build. Firmware analyst Tarun Vats listed fifteen models now in beta.

One UI 8.5, released earlier in 2026, introduced AI Call Screening, real-time voicemail transcription, a Perplexity-powered Bixby, AI-generated wallpapers, Quick Share with Apple AirDrop, a customisable Quick Panel and location-based privacy alerts. One UI 9 continues this platform, emphasizing refinement and accessibility.

The rollout is managed by Samsung’s software engineering division. Independent tracker Tarun Vats monitors firmware releases. Good Lock and its LockStar module provide the primary UI-customisation tools for One UI 9.

The beta list comprises fifteen devices across four flagship generations, four A-series, one M-series and two 2024 foldables. Three S26 beta builds have been issued.

Beta 1 for the Galaxy S26 launched on 13 May 2026, followed by Beta 2 on 26 May and Beta 3 on 16 June, which fixed nine issues including camera preview cropping, 30× zoom focus errors, lock-screen widget updates, S Pen swipe glitches, My Files scrolling, random video-streaming reboots and call-screen glitches. Early July saw internal testing begin for the S23 FE, M34, Z Fold 6, Z Flip 6 and A37, expanding the program to fifteen distinct models.

One UI 9 redesigns the Quick Panel with separate, resizable sliders for brightness, volume and media. Accessibility upgrades add a merged TalkBack screen-reader unifying Samsung and Google tools, a floating “Text Spotlight” zoom, and a high-risk app detection feature that blocks unsigned or suspicious apps before execution. LockStar v9.0.00.5 now fully supports One UI 9.

Samsung’s internal release notes state the company is developing across four flagship generations, four A-series, one M-series and two 2024 foldables simultaneously. Good Lock’s update notes confirm the latest LockStar version adds full One UI 9 support.

Synchronising One UI 9 across legacy and new devices reduces software fragmentation, delivering a uniform experience and bolstering Samsung’s market position against competitors that limit major UI upgrades. Stability fixes and accessibility tools address long-standing user feedback, potentially extending device lifespan and enhancing brand perception.

Samsung will unveil One UI 9 at the Galaxy Unpacked event slated for late July 2026, where pricing, public rollout and live demonstrations of new features are expected.
