While Samsung DeX was originally created to deliver a desktop experience without a PC, the new DeX app will now let you use DeX with your laptop.

Available for the Note10, S20 series and the Note20 series (with new handsets expected to be added in the near future), all you'll need to get started is a PC running Windows 7 or 10, or a Mac running OS 10.13 or higher.

  2. Use your device's charger and connect via the USB port on your laptop or PC.
  3. DeX will automatically begin to load.
  4. From here, you'll have a number of options. You can view DeX in full screen mode, or run it alongside your regular PC applications in a floating window.


With DeX for PC set up, you'll have access to both your PC and Samsung applications at the same time. This means you can continue to browse the web or type on Microsoft Word while also having access to your messages directly on your computer. You can transfer photos from your phone in an instant as well; one swift 'drag and drop' motion will transport your favourite pictures and save them to your PC.
