Use Multi window and App pairs on your Galaxy phone or tablet

Two apps are better than one, and Multi window is better than constantly switching between apps. This feature lets you alternate between apps, adjust the size of the display, and copy information from one app to the other. On top of that, App pairs and Apps Edge make multitasking on your phone or tablet even easier. These features are available on the Galaxy Fold series, the Galaxy Flip series, and non-foldable Galaxy devices as well!
Note: If this is your first time using enhanced edge features, you will have to complete the tutorial. Available screens and settings may vary by wireless service provider, software version, and device model. Split screen view and pop-up view are not supported on the front screen of the Galaxy Z Fold series or Z Flip series. Some apps do not support split screen view.
Customize the Multi window tray
The Multi window tray on the Galaxy Z Flip series and the Galaxy Z Fold series is a convenient menu where you can store apps you frequently use in split screen view or pop-up view. You can customize the tray, so your favorite apps are always right there when you need to multitask.
First, you'll need to open the tray:
Galaxy Z Flip: The Multi window tray has a handle on the right side of the screen. Swipe left on the handle to open up the tray.
Galaxy Z Fold: Swipe left from the screen's right side to open the Multi window tray.
Then, you can start customizing the tray:
Once the tray is open, tap the grid icon to see all of your apps. Or, tap the Edit icon at the bottom.
To add an app to the Multi window tray, just tap it. The app will be added to your Multi app tray.
You can search for more apps to add using the search bar at the top, or by swiping left to view more apps.
When you're done selecting your desired apps, tap Save.

If you have a Galaxy Z Flip, you can take the customization further. Tap the Settings icon in the Multi window tray; from here, you can turn the Multi window tray shortcut on or off, or change which side of the screen the handle appears. If you don’t like where the handle is currently positioned, just drag it up or down the screen’s edge to a new location. Once you are satisfied, tap the switch next to Lock handle position to prevent the shortcut handle from moving.

On the Z Fold and Tab series, you’ll also be able to drag an app from the taskbar to open it in Multi window.

Use apps with the phone folded or unfolded
If you're in a hurry or want to keep things simple, you can view apps in full-screen when your Galaxy Fold series phone is opened or closed.
With your phone folded, tap an app to open it on the front screen. To continue using the app on the main screen, just unfold your phone while the app is open. This feature is great when you find a video you want to watch on the larger screen.
Or, with your phone unfolded, tap an app to open it in full-screen view. Perfect for gaming, reading, or watching videos.
To make using apps even easier, you can also view your suggested apps. Just tap Recents, and apps you've recently used within in the last 3 hours will display at the bottom of the screen.
Multi window on non-foldable devices
With Multi window, you can have two apps open at the same time using split screen view. For example, you can use the calculator for math homework while watching a video.
To access Multi window, tap Recent, which is located to the left of the Home button, unless you've chosen to customize your navigation bar.
Tap the desired app's icon, and then tap Open in split screen view. This app will be pinned to the top window.
Note: Not all apps support split screen view.
To open a second app in the bottom window, simply open the desired app from the list.
You can resize apps by touching and dragging the vertical divider in between the open apps. To close a single app, tap the bar at the top of the app, and then tap the X. To close all the apps in split screen view, just drag the divider in the middle of the screen all the way to the right.
Exit Multi window
When you want to give Multi window a break and just use one app, you can close the split screen view.
To do this, tap the Home button. This will close them completely on the Home screen but leave them together in Recents.

Use Pop-up view
Multi window is really handy, but you can also use the pop-up view feature for even more convenience. This feature lets you make an app's window smaller, and you can even move it around.
Tap Recent, which is located to the left of the Home button.
Tap your desired app's icon, and then tap Open in pop-up view.
Remember, you can use your finger to move the app's window around the screen. You can also adjust the size of the window by touching its sides and dragging your finger vertically or horizontally.

Pop-up view also has other settings to make it easier to use. Here are what the different controls do from left to right:
Opacity: Adjust the window's opacity from transparent to solid.
Floating icon: Minimize the app into a floating icon that you can open up later. You can move the icon around the screen and make more than one app into an icon.
Expand window: Expand the app back into its regular full-screen view.
Close app: Close the current pop-up view window. The app will still open under Recents.
Certain apps, including YouTube, even support a handy picture-in-picture mode. While playing videos or navigating your screen, the app will display in a floating window that you can move around when you exit the app.
Note: Floating windows and picture-in-picture will transfer to the front screen when the "Continue apps on front screen" feature is enabled.
Create an App pair
Note: The Edge panel is available only on certain device models.
Instead of separately opening apps you always use together, create an App pair. That way, those two apps will open simultaneously in split screen view. If you're using the Z Fold2, Z Fold3, or Z Fold4, you can create an App pair with three apps.
Swipe left to open the Apps Edge panel. Touch and hold your desired app, and drag and drop it into the top portion of the screen.
Open Apps Edge again, and then select a second app. Drag and drop it into the bottom portion of the screen.
Tap the divider between the two windows to change the orientation and create an App pair:
Tap the two arrows to swap the apps’ positions.
Tap the App pair icon (it may have a plus sign or a star) to create an App pair. The App pair will be saved, although you may be prompted to select where you'd like to save the App pair to.
If you’d like to add a third app to the App pair, open Apps Edge again, and then drag and drop the new app into your preferred position.
Note: Adding three apps to an App pair is only available on the Z Fold2, Z Fold3, and Z Fold4.
Once all the apps are on the screen, tap the three vertical dots in the center, and then tap the App pair icon. The three apps will be saved in a group.
Useful App pairing ideas
Note: Edge panel is available only on certain device models.
Can’t think of any useful app pairing combinations? Here are some combinations to get those creative juices flowing.
Internet + Samsung Notes: Browse the internet and take notes at the same time.
Play Music + Maps: Play your jam while going on an adventure.
Email + Phone: Never miss an email because of a long phone call.
Camera + Gallery: Capture and manage your photos all at once.

Contacts + Message: Network with your friends and create new connections.
Samsung Notes + Drive: Make a note and save it to your Google Drive.
Remove shortcuts from Apps Edge
Note: The Edge panel is available only on certain device models.
Maybe doing homework while playing a game isn't the best idea. Remove that shortcut to make room for a new one.
From any screen, open Apps Edge by swiping the Edge panel to the left. Tap Menu (the three horizontal lines) at the bottom, and then tap Edit. On some devices, you can simply tap the Edit icon (the pencil). Now you can tap the minus icon next to the shortcuts you want to remove.
You can always add the shortcut back later, or add new Edge panels with additional apps that you'd like to use.
