Use split screen when you want two apps to share the display, and use a floating window when one app should remain above another. The exact commands depend on the tablet maker, Android version and app. On a Pixel Tablet, split screen starts in Overview, the Taskbar or a Home-screen shortcut. On supported Samsung Galaxy tablets, the equivalent movable overlay is called pop-up view. Some large-screen devices also offer Android desktop windowing, with several independent, resizable windows.

Not every tablet or app supports every mode. The steps below identify which instructions are specific to Pixel Tablet, Samsung Galaxy tablets or supported large-screen devices, so you can avoid searching for a control your model does not provide.

Choose the window mode that matches the job

Mode Best for What you can arrange Main limitation
Split screen Keeping two apps visible side by side Two apps, with an adjustable divider Instructions vary by tablet; both apps must support split screen. [Google Pixel Tablet Help; Samsung Support]
Pop-up view (floating window) Keeping one app over another while moving or resizing it One movable overlay, with minimize, maximize and close controls on supported Galaxy tablets Manufacturer-specific controls and app compatibility vary. [Samsung Support]
Picture-in-picture (PiP) Keeping supported video playback visible while you use another app A small movable video window Only apps and video content that implement PiP offer it; it is not a general floating-window switch. [Samsung Support]
Desktop windowing Arranging several independent windows on a large screen Separate windows that can be moved and resized Available only on supported devices, and the experience differs by device. [Google Android Help]

Think of split screen as a fixed two-column layout, pop-up view as one app layered over another, PiP as a special video mode, and desktop windowing as a multi-window desktop. A keyboard, trackpad or external display can expand desktop windowing on devices that support it, but those accessories are not required for ordinary split screen.

Check support before troubleshooting

  • Identify the tablet and software. Menus can differ between manufacturers, models, Android releases and even carrier software. Pixel Tablet instructions are not universal Android instructions.
  • Check the app. Some apps explicitly do not support split screen. If the split or pop-up command is absent for one app but present for another, the app is a more likely constraint than a broken gesture.
  • Separate features that sound alike. A video that shrinks into a movable PiP window is not the same as a Samsung pop-up window, and desktop windowing is not present on every large-screen device.
  • Use the maker’s current help page for the exact model. Samsung notes that available screens and settings can vary by model, software version and carrier. Google likewise warns that desktop windowing is not available on all devices and that the experience may vary.

Pixel Tablet: start split screen

Method 1: From Overview (Recents)

  1. Open the first app.
  2. Swipe slowly up from the bottom edge and hold to enter Overview. If you use three-button navigation, tap the Overview button instead.
  3. Tap the app’s icon at the top of its Overview card.
  4. Choose Split.
  5. Select the second app from the launcher or recent-app choices. It fills the other half of the display.

These labels and the available app list are the Pixel Tablet flow documented by Google; another Android tablet may use a different icon or wording. [Google Pixel Tablet Help]

Method 2: Drag from the Taskbar

  1. Open the first app.
  2. Swipe up slowly until the Taskbar appears.
  3. Press an app icon in the Taskbar and drag it to the left or right edge of the display.
  4. Release it when the split-screen placement is shown.

This method is useful when the app you want is already pinned or visible in the Taskbar. It does not change the requirement that the selected app support split screen.

Method 3: From the Home screen

  1. On the Home screen, long-press the app icon.
  2. Choose Split.
  3. Choose the second app.

If Split does not appear for an app, try another app to determine whether the limitation is app-specific.

Control a Pixel Tablet split-screen pair

Resize the two apps

Drag the middle divider toward either side. The app on the side receiving more space expands while the other contracts. This lets you give a document more room while keeping a narrow reference pane, or reverse the arrangement when the reference needs attention.

Swap their positions

Double-tap the center of the divider. The two apps exchange sides without closing either one.

Save a reusable app pair

On Pixel Tablet running Android 15 or later, you can save the current pair:

  1. Open Overview while both apps are already in split screen.
  2. Tap Save app pair below the pair.
  3. Launch the saved pair from the Home screen later, or add it to the Taskbar.

The save command is tied to the documented Android 15-and-later Pixel Tablet experience. If your tablet is on an earlier release, or the command is missing, continue launching the two apps separately.

Close one side or leave split screen

  • Drag the divider all the way to the side of the app you want to close. The other app remains open.
  • Return to the Home screen to exit split screen completely.

Samsung Galaxy tablets: use pop-up view

Samsung calls its movable overlay pop-up view. The exact screens and settings differ by model, Android/One UI version and carrier, but the Recents route is the clearest documented starting point.

Open an app in pop-up view from Recents

  1. Open the app you want to float.
  2. Open Recents.
  3. Tap the app’s icon above its recent-app preview.
  4. Tap Open in pop-up view.

The app appears in a window above the rest of the interface. If the command is absent, that app, model or software build may not support the mode.

Move and resize the window

  • Drag the pop-up window itself to move it to another location.
  • Drag a side of the window to change its size.
  • Use the window controls to minimize, maximize or close it.

When minimized, the app becomes a floating icon. Tap that icon to reopen the window. This is useful when you need the underlying app unobstructed for a moment but do not want to close the floating app.

Start from the Edge panel

On Galaxy tablets that provide the relevant Edge-panel option, open the Edge panel and drag an app toward the center of the screen. Samsung documents this as another route into pop-up view, but the panel, gesture and available apps vary by device and software.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Pop-up view is not picture-in-picture

Picture-in-picture is a separate Android behavior for supported video apps. When you leave a compatible video app, playback may continue in a small movable video window. The app and the specific video content must support PiP; neither Samsung’s pop-up command nor ordinary split-screen support guarantees it. If a video simply closes or stays full-screen, check that service’s own PiP support and settings rather than looking for a pop-up-window control.

Android desktop windowing on supported large screens

Desktop windowing provides separate app windows that you can move and resize instead of limiting you to two columns. Google explicitly says, “This feature isn’t available on all devices, and the experience may vary.” Treat it as an optional device capability, not a standard Android tablet menu. [Google Android Help]

Open a window from full screen or split screen

  1. With an app in full screen or split screen, drag down the app’s top handle.
  2. Use the window options in the app header to enter the desktop arrangement, when those options are offered.

Use the keyboard shortcut

With a physical keyboard connected, press Action + Ctrl + Down arrow to invoke desktop windowing on a supported device. “Action” refers to the keyboard’s designated Action key; the exact key labeling can differ between keyboards.

Move and resize windows

  • Drag a window by its header bar to reposition it.
  • Drag a corner to resize it with touch.
  • With a mouse, pen or trackpad, you can also resize from an edge.

Keyboard and trackpad behavior

On a supported device connected to an external keyboard and trackpad, apps open in desktop windowing automatically according to Google’s documented behavior. This does not make the feature available on an otherwise unsupported tablet.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Use an external display

Depending on the device and its settings, connecting an external display can mirror the tablet or start a separate desktop session. Google documents that windows can move between the tablet and a connected display, but they cannot be moved onto a display that is currently running a full-screen app. If the second screen shows only a mirror, look for the device’s display-mode setting rather than assuming desktop windowing failed.

Understand what each mode can and cannot do

Split screen is the predictable choice when both tasks need steady space. It keeps two app panes visible and gives you one divider to adjust, but it is still a two-app arrangement. A third app will normally replace one of those panes unless the device offers a different windowing mode. The divider is therefore a layout control, not a way to create unlimited columns.

Pop-up view is more flexible spatially because the overlay can be moved over the underlying app and resized from a side. On Samsung, minimizing does not close the app; it turns the window into a floating icon that you can tap again. That behavior is different from leaving an app in split screen and different from PiP, whose controls and availability belong to the video app.

Desktop windowing is the broadest option, but it has the strictest device requirement. It is intended for supported large screens and can expose separate headers, corners and (with a mouse, pen or trackpad) edge handles. A keyboard shortcut or connected keyboard and trackpad can make entry easier, yet an accessory cannot add desktop windowing to a tablet that does not implement it.

Which mode should you use?

If you need to… Start with… Why
Read one app while entering information in another Split screen Both apps remain visible, and the divider lets you allocate more space to the active task.
Keep a small utility over a main app Pop-up view on a supported Galaxy tablet The window can move, resize, minimize to an icon and return without closing.
Watch supported video while doing something else Picture-in-picture It is designed for a small movable video window, but only compatible apps and content provide it.
Arrange three or more independent windows Desktop windowing on a supported large-screen device Windows have separate headers and resize handles, with optional keyboard, trackpad and display support.

Troubleshoot common failures

The split or pop-up command is missing

  • Try a different app. Missing support in only one app usually indicates an app compatibility restriction.
  • Confirm you are following the instructions for your manufacturer. Pixel’s Split command and Samsung’s Open in pop-up view are not interchangeable labels.
  • Check the tablet’s software version and the manufacturer’s current support page. Samsung says settings can vary by model, software and carrier.

The second app will not open

Close the attempted layout, then select a known compatible app from the available choices. If the second app never appears, the tablet may restrict that app from split screen or the feature may not be implemented on that model.

The floating window is in the way

On a Galaxy tablet, drag it to another area, resize it from a side, or tap minimize to turn it into a floating icon. Tap the icon when you need it again. If you are using PiP, move the video window instead; PiP controls are governed by the video app.

Desktop windowing does not appear

Verify that the tablet is a supported large-screen device. Try dragging down the app’s top handle or opening the app-header window options. With a physical keyboard, try Action + Ctrl + Down arrow. If none of these controls exists, Google’s availability warning applies: the feature is not universal.

An external display mirrors instead of extending

Mirroring and a separate desktop session are both documented possibilities. Check the tablet’s display settings and whether the attached display is occupied by a full-screen app; windows cannot move onto a display running that mode.

  • Use desktop windowing only when the large-screen device supports it.
  • Carry the tablet model, Android/software version and app compatibility into every troubleshooting decision.

Frequently Asked Questions

Can I use the Pixel Tablet split-screen steps on any Android tablet?

No. Overview, Taskbar and Home-screen commands described here are documented for Pixel Tablet. Other manufacturers may use different icons, labels or entry points, so check the help page for your exact model.

Why is the Split option missing?

The app may not support split screen, or your tablet may use a different command. Try a second app. If Split appears for that app, the first app is likely the limitation. Also verify the tablet model and software version.

How do I resize split screen on a Pixel Tablet?

Drag the center divider toward either side. The pane receiving more space expands while the other contracts. Double-tap the divider’s center to swap the apps’ positions.

How do I save two apps as a shortcut?

On a Pixel Tablet running Android 15 or later, open Overview while the pair is already split, tap Save app pair, then launch the saved pair from the Home screen or add it to the Taskbar.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

What is Samsung pop-up view?

It is Samsung’s name for a movable overlay window. From Recents, tap the app icon above its preview and choose Open in pop-up view. You can drag the window, resize it from a side, and minimize, maximize or close it.

Does minimizing a Samsung pop-up close the app?

No. Minimizing changes the window into a floating icon. Tap that icon to reopen the app window; closing it uses the close control instead.

Is picture-in-picture the same as a floating window?

No. PiP is a separate behavior for supported video apps and content. A compatible video can continue in a small movable window after you leave it, but ordinary pop-up or split-screen support does not guarantee PiP.

Can every Android tablet use desktop windowing?

No. Google says desktop windowing is not available on all devices and that the experience varies. It is an optional feature on supported large-screen devices, not a universal Android setting.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

How do I enter desktop windowing?

On a supported device, drag down an app’s top handle from full or split screen, use the app header’s window options, or press Action + Ctrl + Down arrow with a physical keyboard. A supported tablet with an external keyboard and trackpad can open apps in desktop windowing automatically.

Can I move desktop windows to an external monitor?

Depending on the device and settings, the monitor may mirror the tablet or run a separate desktop session. Google says windows can move between the tablet and connected display, but not onto a display currently occupied by a full-screen app.

The Bottom Line

Use split screen for two apps that need consistent side-by-side space, Samsung pop-up view for a movable overlay, and PiP only for compatible video. Choose desktop windowing only when your large-screen device supports it. If a command is missing, check the tablet model, software version and app compatibility before treating it as a fault.
