Two days ago, Samsung released the third beta version of One UI 4.0 to the Galaxy Z Flip 3 and the Galaxy Z Fold 3. The update fixed multiple bugs, including the one that caused the screen to stutter and the one that caused brightness issues. It has now been revealed that the update also includes the latest security patch.
The latest One UI 4.0 beta build, which comes with a firmware version ending ZUKG, brings along the December 2021 security patch. The Galaxy Z Flip 3 and the Galaxy Z Fold 3 running One UI 4.0 Beta are the first smartphones to receive the December 2021 security update. Samsung hasn’t revealed which vulnerabilities it has fixed with the new security patch, but we expect that to be revealed in the first half of next month.
The Android 12-based One UI 4.0 update brings a revamped UI design, smoother animations and transitions, Material You-inspired Color Palette feature, and improved privacy and security. The update also includes new widget styles, additional widgets, and a new widget picker UI. Samsung has also improved all of its stock apps, including Samsung Internet and Samsung Keyboard.
The stable version of One UI 4.0 has already been released to the Galaxy S21 series in various markets, and the Galaxy Z Flip 3 and the Galaxy Z Fold 3 could get a stable update sometime next month.
