Samsung Galaxy Z Fold 4 and Z Flip 4 are now receiving the new One UI 5.1.1 update. The update is now in the expanding phase; it was initially introduced on the Galaxy Z Fold 4 and then expanded to other devices. But due to carrier restrictions in the US, several units of these devices haven’t gotten the update yet, but now carriers are gradually updating them as well.

The carrier-locked units of the Galaxy Z Fold 4 and Flip 4 are now getting the One UI 5.1.1 update on Verizon. The latest update for these devices comes with firmware version numbers F936USQU3DWH5 and F721USQU3DWH5, respectively. The update was also previously available on two more carriers, including T-Mobile and MetroPCS.

One UI 5.1.1 brings new features to several applications

One UI 5.1.1 brings several new enhancements under several system applications, including Gallery, Camera, Samsung Health, Quick Share, and Device Quick Share. Additionally, Samsung has added some new functionality to different stock features like the Flex Mode Panel, Multiwindow, and Taskbar.

Moreover, the new update will refresh almost all the elements of Galaxy foldables, so if you install the latest update on your device, you will get better performance, stability, and more control over functions.

It is also worth noticing that both of the devices will also get a new security patch in August 2023. It includes over 80 fixes that enhance the security of the device and strengthen it against external threats.

1. Open the system settings.
2. Tap on the software update menu.
3. Touch the first option, “Download and Install.”
4. Now wait for some time to search.
