DeX mode turns your tablet into a desktop-like workspace — here's how to exit it

DeX mode is Samsung's desktop environment that lets you use your tablet with a mouse, keyboard, and external monitor. When it's on, your tablet displays a Windows-like interface with a taskbar and resizable windows. To turn it off, you swipe up from the bottom of the screen to open the app drawer, find the DeX icon (it looks like a monitor), and tap it to toggle the mode off. Your tablet returns to its normal mobile interface when ready.

The exact steps depend on which Samsung tablet model you have and which version of Android it runs, but the core method works across most recent devices. If you're using DeX with an external display, disconnecting that display will also exit DeX mode automatically on some models.

Key Takeaways

  • DeX mode is toggled on and off through the app drawer or the quick settings panel, depending on your tablet model.
  • Swiping up from the bottom of the screen opens the app drawer where you'll find the DeX toggle icon.
  • If you're using an external monitor, unplugging it will exit DeX mode on most Samsung tablets.
  • Some tablets let you turn off DeX from the notification panel by swiping down twice from the top of the screen.

The quickest way: using the app drawer

On most Samsung tablets running Android 9 or later, the fastest route is through the app drawer. Swipe up from the bottom center of your screen — the same gesture you'd use to go home. This opens your full list of apps and system shortcuts.

Look for an icon labeled DeX or Samsung DeX. It typically shows a small monitor symbol. Tap it once to toggle DeX mode off. Your tablet will return to the normal mobile layout within a few seconds, and any windows or apps you had open in DeX will close or minimize.

Using the quick settings panel if the app drawer doesn't show DeX

Some Samsung tablet models don't display the DeX toggle in the app drawer. Instead, you'll find it in the quick settings panel. Swipe down from the top of your screen twice — once to open the notification shade, and a second time to expand the full quick settings grid.

Scan the grid for a DeX tile. If you don't see it when ready, swipe left or right within the quick settings area to reveal more options. Tap the DeX tile to turn the mode off. If the tile isn't visible at all, your tablet may not have DeX installed, or it may be disabled in your system settings.

Disconnecting an external monitor or dock

If you're using DeX with an external display, keyboard, or Samsung DeX dock, straightforward unplugging the monitor cable or removing your tablet from the dock will exit DeX mode on most devices. The tablet detects the disconnection and automatically switches back to mobile mode.

This is often the easiest method if you're actively using an external setup. You don't have to navigate menus — just unplug and your tablet returns to normal. If your tablet stays in DeX mode after disconnecting, use one of the methods above to manually turn it off.

What to do if DeX won't turn off

If you've tried the app drawer and quick settings but DeX mode is still active, restart your tablet. Hold the power button until the power menu appears, then select Restart or Power off. Wait 30 seconds, then turn the tablet back on. This clears any software glitch that might be keeping DeX locked on.

If DeX still won't turn off after a restart, check whether your tablet is connected to a Samsung DeX dock or external display that's forcing the mode to stay active. Disconnect all external devices and try again. If the problem persists, you may need to check your tablet's developer settings or contact Samsung support, as a deeper software issue could be at play.

Disabling DeX entirely if you don't use it

If you never plan to use DeX mode, you can disable it in your tablet's settings to prevent accidentally turning it on. Open Settings, then go to Apps or Applications. Search for Samsung DeX or DeX.

Tap the app, then select Disable or Turn off. Your tablet will remove the DeX toggle from the app drawer and quick settings. You can re-enable it later by returning to the same menu and selecting Enable if you change your mind. Disabling DeX doesn't delete any of your files or settings — it just hides the feature.

Why your tablet might be in DeX mode without you realizing it

DeX mode can set up automatically if your tablet is connected to a Samsung DeX dock, an external monitor via USB-C, or a compatible keyboard dock. Some users turn it on by accident while exploring settings or when a family member borrows the tablet. If you find yourself in DeX mode unexpectedly, check whether any external devices are plugged in.

Another common cause is a shortcut or automation you may have set up. If you use Bixby routines or other automation apps, one of them might be triggering DeX at a certain time or location. Open your automation settings and look for any routines that mention DeX, then disable or edit them as needed.

Frequently Asked Questions

Does turning off DeX mode delete my files or apps?

No. Turning off DeX mode only changes how your tablet displays its interface. All your files, apps, and data remain on your device. Any open windows or documents in DeX will close, but the apps themselves are still installed and ready to use.

Will my external monitor stay connected if I turn off DeX?

The monitor will remain physically connected, but it will go blank or show no signal once DeX mode is off. Your tablet stops sending video to the external display when DeX is disabled. You can reconnect and re-enable DeX at any time by plugging the monitor back in or toggling DeX on again.

What's the difference between turning off DeX and disabling it?

Turning off DeX exits the mode temporarily but leaves the feature available in your settings. Disabling DeX removes it from your quick settings and app drawer entirely. Disabling is useful if you never plan to use it; turning it off is better if you use it occasionally and just want to exit it now.

Can I turn off DeX if my tablet is frozen in DeX mode?

If your tablet is unresponsive, restart it by holding the power button for 10 to 15 seconds until it shuts down. Wait 30 seconds, then power it back on. This will exit DeX mode and clear any software freeze. If the tablet remains stuck, try a factory reset as a last resort, though this will erase all data.

Why does my tablet keep going back into DeX mode?

This usually happens if an external device like a dock or monitor is still connected. Check for any USB-C cables, docking stations, or monitors plugged into your tablet and disconnect them. If nothing is connected, look for automation routines in your settings that might be turning DeX back on automatically.
