Samsung is actively rolling out the June 2025 security update to eligible Galaxy devices. After a number of models received the patch last week, it is now the turn of the Galaxy Z Fold 3 and Galaxy Z Flip 3.

Soon after completing the patch release for the Galaxy Z Fold 6 and Z Flip 6, Samsung continues to bring the June update to the previous generation of foldable phones. This update is currently starting in the Korean market and will soon expand to other regions in the next few days.

The update for the Galaxy Z Fold 3 has the software code F926NK559KYF1, while the Z Flip 3 has the code F711NKSSAKYF1. This is a minor software update, mainly integrating the June security patch, not adding new features, but focusing on fixing security vulnerabilities discovered in the previous version.

In addition to improving security, this update also improves the overall stability and performance of the system. Users can expect smoother, more stable, and more optimized performance during daily use.
