This new update only includes the May 2024 security patch, which fixes over four dozen security vulnerabilities. It doesn't bring any new features or performance improvements. For a more feature-packed update, you have to wait for One UI 6.1.1, which will be based on Android 14. However, it will arrive after the launch of the Galaxy Z Flip 6 and the Galaxy Z Fold 6 in the second half of this year.
