Samsung is accelerating its internal testing phase for the flagship Galaxy S26 series, but the software journey is far from over. Two brand-new One UI 9 builds have just been spotted on official update servers, confirming that developers are actively refining both the public testing branch and the upcoming official release candidate.
The discovery highlights Samsung’s dual-track update strategy as it works through critical user feedback following the recent One UI 9 Beta 5 rollout.
The Newly Spotted One UI 9 Build Versions
Following the widespread release of Beta 5 (Build ZZH6), tracking logs show two fresh builds actively undergoing internal evaluation:
Stable Test Candidate:
S948BXXU4BZHABeta Test Candidate:
S948BXXU4ZZHB
The ZZHB build follows Samsung’s strict versioning code reserved exclusively for beta software, confirming that One UI 9 Beta 6 is coming in the next few weeks.
Samsung’s parallel work on the BZHA candidate means engineers are laying the groundwork for the final public rollout while maintaining an active testing sandbox for remaining bug fixes.

Why One UI 9 Beta 6 is Necessary
While Beta 5 resolved several major system crashes and battery-drain issues, daily feedback from community testers confirms that performance is not yet smooth enough for a stable rollout.
Key issues driving the need for Beta 6 include:
Notification Panel & Dropdown Lag: Swiping down the Quick Settings menu frequently triggers stuttering, frame drops, and delayed touch responses.
UI Micro-Stutter: General navigation between recent apps, home screen widgets, and app launching still experiences noticeable performance hiccups.
Animation Inconsistencies: Control tiles, quick toggles, and system pop-ups occasionally stutter or freeze mid-animation.
What Galaxy S26 Users Can Expect Next
The dual appearance of builds BZHA and ZZHB signals that Samsung is entering the final polishing phase of its update cycle.
Timeline: Expect One UI 9 Beta 6 to arrive within the next 2 to 3 weeks to fix remaining drop-down menu stuttering and UI animation bugs.
Stable Rollout: Once Beta 6 stabilizes system animations, Samsung will finalize the BZHA build for global deployment across all Galaxy S26 variants.
