Samsung DeX has been a flagship feature since 2017, allowing Galaxy devices to function as desktop computers. While traditionally requiring an external display, users can now run DeX directly on the Galaxy Z Fold 8's inner screen. This is achieved through the Gadesk app, available on the Google Play Store, which avoids the need for rooting or complex hacks. To set up the feature, users must first disable Auto Blocker in settings and enable wireless debugging in Developer options. After pairing the device, the app tricks the Z Fold 8 into recognizing an external display, projecting the desktop interface onto the 7.6-inch foldable screen.

Once configured, users can adjust orientation settings, switching from the default landscape to portrait for better multitasking. The app also offers a virtual trackpad with copy, paste, and zoom functions. A gesture action menu provides additional control options. This method transforms the Z Fold 8 into a portable workstation, leveraging its large inner display for a full desktop experience without needing a monitor, keyboard, or mouse connected externally.
