After last month’s Samsung One UI 5.1.1 beta, the official version for last year’s Galaxy foldable phones, Galaxy tablets and Galaxy smartwatches is finally here. The update is slated to arrive on the Galaxy Z Fold4 and Z Flip4 this month, while the Z Fold3, Z Flip3, Z Fold2 and Z Flip are expected to receive the latest One UI build at a later date. The older foldables will inherit several features from the current Samsung Galaxy Z Fold5 and Galaxy Z Flip5 models. This includes the customizable toolbar for the Flex Mode panel.


Multi-window mode allows you to open two apps at the same time without interrupting media playback. This also applies to older foldable phones with Samsung One UI 5.1.1. The hidden pop-up feature for the Galaxy Z Fold4, Z Flip5 and the Galaxy Tab S8, Tab S8+ and Tab S8 Ultra allows you to reposition apps, switch between them or assign them to one half of the screen.


You can switch from pop-up view to multiple windows by simply pressing and holding the pop-up window’s taskbar. Two-handed drag-and-drop lets you quickly select multiple files and then drag them to other apps in the taskbar for editing or sending. This feature is coming to Samsung tablets and foldables of the Korean manufacturer.
Samsung Galaxy Watch
The Samsung Galaxy Watch5 and Galaxy Watch4 get the new One UI sleep insights features. This includes a detailed sleep score report with readings for each sleep stage.


Users of an older Samsung Galaxy Watch also get new watch face options and a camera control function. This allows you to use your smartwatch on compatible Galaxy smartphones as a remote trigger for the cameras.
