2. Then, tap the Samsung DeX icon. If it's your first time using this feature, follow the instructions.
   
3. The DeX interface will load on the tablet the same way it appears on desktops and monitors.
4. You can navigate DeX using the touch screen, S Pen, a USB or Bluetooth mouse and keyboard, or a Keyboard cover.
   

To exit standalone DeX, open the Quick settings panel again, and then tap the Samsung DeX icon.

Samsung DeX on Galaxy tablets running Android 16 with One UI 8.0 or higher now also allows you to launch apps directly from the Home screen in pop-up view to switch to DeX mode. Here's how:

1. Launch any app on the Home screen, and then swipe down on the header bar (a horizontal line) in the top center of the app window to switch the app to pop-up view.
2. You can open multiple apps and move or resize pop-up windows for enhanced multitasking in a desktop-like workspace.
3. To set up another workspace, select the Recent icon at the bottom corner, and then select the Add desktop icon (it looks like a monitor with a plus sign) in the middle right.
   
   Note: You can create up to four workspaces. 
4. While in the Recents view, swipe left or right to view your additional workspaces.
   

To exit DeX mode from the Home screen, select the Recent icon again, then select the Home screen icon in the middle-left, or select the X in the top-right corner of the workspace to close the desktop workspace(s). 

Although DeX mode on tablets doesn’t require cables, you can still connect it to a bigger TV or a smart monitor if you’d like.

1. Navigate to and open Settings on your tablet, then tap Connected devices, and then tap Samsung DeX.
   
2. Tap Connect wirelessly. If prompted, review and allow the permissions.
   
3. Select your TV or smart monitor from the list, and then tap Start now.
   
4. Your TV or smart monitor will prompt you to select Allow before connecting.
5. Tap Start on your tablet to allow the necessary permissions. If another Samsung DeX pop-up appears, tap OK. 
6. You can navigate DeX using the Touchpad icon (it looks like a small box) in the lower corner of the screen, an S Pen, a USB or Bluetooth mouse and keyboard, or a Keyboard cover.
   Note: You can perform basic operations using the touchpad, but some gestures, such as pinching with two fingers to zoom in, won’t work with the Touchpad.

To exit DeX mode, tap the DeX icon from the Quick settings on your tablet. Or navigate to and open Settings, then tap Connected devices, then tap Samsung DeX, and then tap Disconnect.

The following tips will help you when connecting wirelessly to a TV or monitor:

• Maintain a short distance between your tablet and TV or smart monitor for a stable wireless connection, avoiding stuttering or lagging.
• Remote DeX access from a Samsung TV may not work properly if your tablet's screen is turned off.
• If facing connectivity issues, turn on your tablet's screen before reconnecting. While basic operations are possible with a PC-connected touchpad, gestures like two-finger pinching for zooming are not supported.
• Touchscreen displays are not compatible with DeX functionality.

A DeX cable, an HDMI-to-USB Type-C cable, or an HDMI adapter enables you to directly connect your tablet to a TV or monitor without requiring extra accessories. Follow the steps below to set up DeX:

1. Plug the USB-C end of the DeX cable or HDMI cable into your tablet. Then, connect the other end of the cable to the HDMI port on your TV or monitor.
2. Unlock your tablet if prompted. If it's your first time using DeX, a pop-up message will appear on the Home screen. Tap Start to enable Full Desktop mode.
   Note: If the pop-up doesn't appear, swipe down with two fingers to open the Quick Settings panel, and then tap the DeX icon.
3. If your TV or monitor automatically mirrors your tablet's screen, swipe down from the top left side of the screen to open the Notification panel. Tap the Samsung DeX notification, then select Samsung DeX to switch to DeX mode. Or, swipe down with two fingers to open the Quick Settings panel and select the DeX icon.
   
4. If another Samsung DeX pop-up appears, tap OK. 
5. You can navigate DeX using the Touchpad icon (it looks like a small box) in the lower corner of the screen, an S Pen, a USB or Bluetooth mouse and keyboard, or a Keyboard cover.
   
   Note: Basic touchpad operations are supported, but gestures like two-finger pinching for zooming are not.

To exit DeX mode, tap the DeX icon from the Quick settings on your tablet, or disconnect the DeX cable or HDMI cable from your tablet.

If you're facing challenges with text readability in DeX mode, need to tweak display settings for your connected screen, or want to adjust mouse and keyboard configurations, you can manage these preferences via the Samsung DeX menu.

1. Open Settings and select Samsung DeX.
2. From this menu, you can personalize your DeX experience:
   
   • Adjust the connected display settings
     • Wallpaper
     • Font size
     • Display resolution
     • Display rotation
     • Screen timeout
   • Modify keyboard, mouse, or touchpad settings.
   • Change your sound output between the tablet and display.

These options allow you to tailor DeX mode to your preferences and improve usability.
