Galaxy Z Flip 7, Fold 7 get December 2025 security update

Samsung is rolling out the December 2025 security update to the Galaxy Z Flip 7 and the Galaxy Z Fold 7 in Korea.

Earlier this week, Samsung opened the beta program for the next version of One UI for Galaxy smartphones, One UI 8.5. So far, the company has offered it only to the Galaxy S25 series. The next devices in line to get it are expected to be the Galaxy Z Fold 7 and the Galaxy Z Flip 7. Well, before the South Korean tech giant does that, it is offering an update to the two phones.

Samsung is rolling out a software update to the Galaxy Z Fold 7 and the Galaxy Z Flip 7. It offers the December 2025 security patch, which fixes 57 security issues present in the previous version of the OS. Currently, the brand is offering the update in its home country, South Korea. The updates carry firmware versions F966NKSS6AYKE and F766NKSS6AYKE.

We expect the brand to release the update in other regions in the next few days. To check for the update, go to Settings > Software update > Download and install.

Coming back to One UI 8.5 for the Galaxy Z Fold 7 and the Galaxy Z Flip 7, a few days ago, a Samsung official firmware for the former containing One UI 8.5 leaked. We tried it on our Galaxy Z Fold 7, and here's what we found.
