Samsung has pushed a fresh update with the May 2025 security patch for Galaxy Z Flip 6 and Galaxy Z Fold 6 smartphone users. The update is currently rolling out for users in Korea, and the company will soon make it available for all models.

Users of the Samsung Galaxy Z Fold 6 and Galaxy Z Flip 6 smartphones are getting the May 2025 security update with One UI build versions F956NKSS2BYDD and F741NKSS2BYDD, respectively. It is an initial rollout, so it may take some hours or days to reach all models.

Following One UI 7 resumes with the April patch, this is the first software update Samsung is rolling out for Galaxy Z Flip 6 and Galaxy Z Fold 6 users. This new software makes the device’s features more stable and secure.

May 2025 security patch brings important fixes to improve the safety of Galaxy devices. The update addresses 58 high-level security issues found by Google that affect all Android phones. In addition, Samsung fixed 20 more problems specific to Galaxy devices, including 13 that were explained in detail. These focus on One UI to make Galaxy phones more secure.

The installation package size of this update is around 425 MB. You can download the update via Settings >> Software Update >> Download and install. If you have received the update, install it now to enjoy enhanced features.

One UI 8 for Galaxy Z Flip 6, Fold 6

Samsung has already started One UI 8 internal testing for the Galaxy Z Flip 6 and Galaxy Z Fold 6, along with the Galaxy S25 smartphones. The Galaxy Z Flip 6 smartphone was also spotted running Android 16 on the Geekbench platform, scoring 1749 and 3941 points in single-core and multi-core tests. It is expected that Samsung will start the One UI 8 Beta Program in late May 2025 or early June 2025.

The May 2025 security update is starting to roll out to the Galaxy S24 series. It’s the first official firmware update after Samsung deployed the Stable One UI 7. Global users, including in the US, should expect the OTA within a week.

Samsung’s BYDF update installs the latest May 2025 security patches on Galaxy S24, S24+, and S24 Ultra. Unlike the S25 series, it’s not a Seamless Update, so you will have to face a little more downtime during installation.

The update is available at different carriers in South Korea. A notification for the OTA would appear on your device, while you can manually speed up the process by fetching the update through the Software update section under Settings.

Firmware versions:

• Galaxy S24 – S921NKSS4BYDF
• S24 Plus – S926NKSS4BYDF
• S24 Ultra – S928NKSS4BYDF

One UI 7-based security patch

The changelog suggests the release focuses on security improvements. Additional enhancements for system stability and app functioning are included. But what makes it more meaningful is its arrival after the recent major upgrade.

Last month, Samsung concluded the Beta Program and released the Stable One UI 7 update. The major OTA has reportedly caused excessive battery drain problems. Some users also found “very minor” flaws across the operating system.

The May 2025 software update should address the errors causing excessive battery consumption. System animations and functional stability should also be enhanced to deliver a better overall user experience.

May patch includes fixes for 58 CVEs from Google and 20 from Samsung.

Samsung is rolling out the One UI 7 update to several Galaxy devices. Owners of Samsung’s flagship phones, foldables, and tablets have received the update in several markets, while select Galaxy A phones have also joined the party.

Android 15-based One UI 7 introduces a brand new interface. The Quick Settings and Notification Panel are redesigned to offer a fresh feel. Icons are modern and dynamically colored, while shapes are unified to offer a unified look.

Now Bar is available across the entire Galaxy lineup, while the lock screen placement differs. The position of the in-screen fingerprint area is the key factor behind alignment, while it’s at the middle of the screen on non-premium devices.

Samsung devices getting the One UI 7 update gain new features and UI changes as per their hardware specifications. The company has tried to expand features as much as it can, but the availability is not universal.

Here’s a list of devices that have received the update so far:

Galaxy S Series

• Galaxy S24 series
• Galaxy S23 series
• Galaxy S22 series
• Galaxy S21 series
• Galaxy S24 FE, S23 FE and S21 FE
