Perhaps the reason Samsung has just started rolling out the March 2026 security patch update is because of the One UI 8.5 beta update. The Korean company recently opened the beta program to more devices, which brought the latest security patch. Now, the Galaxy Z Fold 5, Fold 4, Flip 5, and Flip 4 are receiving the update.
According to the Google security bulletin for March 2026, over 120 security vulnerabilities were patched. They range from high to critical, and we recommend installing it when prompted. Aside from enhancing security and optimizing performance, there are other features under the hood.
