Before Android 14-based One UI 6, the One UI 5.1.1 update is rolling out to install additional new features and enhancements. Most of the features are derived from the latest Samsung foldables, continuing the commitment to deliver refreshed smartphone experience.

Here’s the changelog:

Multitasking

Better app previews on the Recents screen

• The Recents screen now shows apps as they will appear after you open them. You can easily see if an app is opened in split screen, full screen, or as a pop-up.

Easily switch from pop-up view to split screen

• Press and hold the handle at the top of the pop-up window, then drag the app to the side of the screen where you want it to be shown.

Restore pop-ups snapped to the edge of the screen

• Drag an app in pop-up view to the edge of the screen to snap it to the edge and keep it out of the way. When you need it again, tap anywhere on the pop-up to bring it back to its previous location.

Flex mode

Use the Flex mode panel with more apps

• More apps can now be used with the Flex mode panel. When the Flex mode panel is turned on, just fold your phone upright and tap the button that appears on the navigation bar.

Improved media controls

• Buttons for skipping forward and backward 10 seconds are now available on the Flex mode panel. When you touch the time bar, the time you’ll move to will be shown to help you find the right moment.

Customize the toolbar

• Create your own personal layout to quickly access features like split screen view, screen capture, and more. Touch and hold an icon on the Flex mode panel toolbar to reorder the icons or move icons into or out of the toolbar.

Quick Share

Share with contacts

• You can now send files to your contacts anytime, even if they’re not near you.

Share files privately

Camera and Gallery

More date and time styles for watermarks

Enhanced remaster previews

• Thumbnail images are now shown below the image you’re remastering. Tap a thumbnail to compare the remastered image to the original with a larger view.

Apply effects more easily

Copy and paste effects

Additional changes

Drag and drop with two hands
