Samsung Starts One UI 9 Beta Testing on Galaxy S23, S24 and A56 Series

Samsung released the June security update that patched a local attacker vulnerability and is now expanding the One UI 9 beta to additional phones. Firmware tracker Tarun Vats confirmed internal testing has started for the Galaxy S23 series, the Galaxy S24 series and the Galaxy S24 FE. A first internal build for the Galaxy A56 has also been spotted.

The Galaxy S26 is already on Beta 3 of One UI 9, while the Galaxy S25 is next in line for the public beta. Samsung is therefore running One UI 9 development across four generations of flagships and one mid-range device at the same time. Beta 3 for the Galaxy S26 fixed camera preview cropping, lock screen widget errors, S Pen home screen swipe issues and a bug that caused random reboots during video streaming.

The same build added a Quick Panel icon for Summarise Notifications, and Samsung states that the summaries are AI-generated. It also introduced smoother animations. Gemini Intelligence is not yet included in the One UI 9 beta.

The feature arrives with the Galaxy Z Fold 8 in July and will be available on every eligible device after the July 22 launch. Devices currently receiving One UI 9 beta updates are the Galaxy S26, S26+ and S26 Ultra. Devices in internal testing are the Galaxy S25, S25+, S25 Ultra, S25 Edge, S24, S24+, S24 Ultra, S24 FE, S23, S23+, S23 Ultra and A56.

The Galaxy Z Fold 8 Ultra, Galaxy Z Fold 8 and Galaxy Z Flip 8 will launch with stable One UI 9 on July 22.
