Samsung has officially begun releasing the Android 16-based One UI 8 beta update for select flagship devices, including the Galaxy S24 series, Galaxy Z Fold 6, and Galaxy Z Flip 6. The beta is currently live for users in South Korea and the UK, with more regions set to join soon.

The update not only delivers early access to Samsung’s latest custom interface but also integrates the August 2025 security patch, making it both a functional and secure upgrade for beta testers.

One UI 8 Beta Now Available for Galaxy S24 Series

According to multiple reports from user posts on X (formerly Twitter), the beta rollout has reached the Galaxy S24, Galaxy S24+, and Galaxy S24 Ultra in the UK and South Korea. The firmware versions for the update are reportedly S926BXXU9ZYH3, S926BOXM9ZYH3, and S926BXXU9CYH3 in the UK.

The One UI 8 beta 2 package is approximately 3.2GB in size, meaning users should have sufficient storage and a stable Wi-Fi connection before downloading. Apart from the UI changes and performance improvements, the update includes Samsung’s August 2025 security patch, addressing key vulnerabilities.

Samsung’s latest foldables, the Galaxy Z Fold 6 and Galaxy Z Flip 6, have also started receiving their first One UI 8 beta in South Korea. Early testers report smoother animations, upgraded multitasking capabilities, and refined Flex Mode enhancements.

Just like with the Galaxy S24 series, the update for foldables also includes the latest security improvements, making it a stability-focused yet feature-rich upgrade.
