This release focuses on security, addressing a total of 55 vulnerabilities in the system. These fixes come from Google (23 patches, with two not applying to Samsung devices), Samsung Semiconductor (4 patches), and Samsung Mobile (30 patches). Samsung classifies one as critical, 28 as high-risk, and three as moderate-risk.
The update brings no new features or visible changes—it’s purely about keeping the devices protected against potential threats.
Rollout Details
Samsung began the rollout in South Korea, its home market, which is the usual starting point. From there, it spreads to other regions over the next few days or weeks. The process happens in stages, so not every user will see it right away.
For the Galaxy Z Flip 6, the update size is around 390MB, with firmware version F741NKSS2CZA1 (spotted on Samsung Community forums). Similar details apply to the Galaxy Z Fold 6, though exact firmware may vary by model variant.
These foldables run on Android 16 with One UI 8.0. Owners can expect the next major step, One UI 8.5, sometime soon.

How to Check for the Update
Head to your phone’s Settings > Software update > Download and install. If it’s available, follow the prompts to grab it. A restart usually finishes the process.
This monthly security maintenance helps maintain device stability and protection. Samsung’s commitment to regular patches remains strong for these 2024 flagships, which are eligible for seven years of OS and security support overall.
