Galaxy Z Flip 5 and Galaxy Z Fold 5 will be the first to run Samsung's One UI 5.1.1 interface

The next version of Samsung's One UI interface, One UI 5.1.1, is currently being tested on the South Korean variants of the Galaxy Z Flip 5 (SM-F731N) and the Galaxy Z Fold 5 (SM-F946N). As per SamMobile, the foldable clamshell Galaxy Z Flip 5 was spotted on Samsung's servers running One UI 5.1.1 thanks to firmware version F946NKSU0AWD5. The Galaxy Z Fold 5 was seen with One UI 5.1.1 firmware version F731NKSU0AWD5.

Both of the firmware versions are based on Android 13 and after One UI 5.1.1 debuts on the foldable models, it will probably be disseminated to other Galaxy phones and tablets. The One UI interface was created by Samsung as a way for those with large-screened devices to reach all of the tappable elements on the screen. This is done by moving these elements to the bottom of the display from the top.
