Samsung DeX

Community Manager





Please Note: Samsung DeX is available on selected mobile devices and is compatible with Windows 7 or 10 and Mac OS 10.13 or higher. Desktops require at least 500MB of free disk space.


From phones that fold to AI assistants, our imaginations have never been freer to reinvent ways of using and fusing our technologies. Samsung DeX is a powerfully versatile player in this field — a native application that offers a desktop-like interface powered by your mobile device



All you need to do is connect your mobile device to a monitor (optional for tablets), and a keyboard and mouse if you're feeling fancy 😎, and launch Samsung DeX. From there, you can take advantage of many desktop features such as dragging and dropping files, arranging and resizing windows and utilising keyboard shortcuts.


We really do love this feature — with optimised apps like Adobe Photoshop Lightroom, Zoom, YouTube and Microsoft Office Suite, Samsung DeX is a real powerhouse for flexible, remote working. You can also get the best of both worlds by storing private documents safely on your phone using Secure Folder, then viewing or presenting them later on a big screen without having to transfer sensitive files.


It's not all work and no play though. With Samsung DeX you can kick back and stream movies to a big juicy TV or monitor, while still using your a phone. Stream videos, films, photos and artwork to the big screen but respond to calls and messages as normal on your handheld device. You can even connect to a PC or Mac for creative cross-platform multitasking and file sharing. 



Samsung DeX for mobile device and monitor:

For a desktop-style experience using a phone or tablet, you'll need an external display such as a monitor or TV, as well as an HDMI to USB Type-C adaptorSome newer models support USB Type-C directly, allowing you to connect using a USB Type-C to USB Type-C cable without an adapter. 


Refer to the user manual of your monitor or TV to see which connections are supported.  For some smartphone models, you may also wish to use a DeX Station or DeX Pad. 



  1.  Find a suitable space and get set up
    • Remove your phone's case if it has one.
    • If using a DeX Station or DeX Pad, attach the charging cable to the dock
  2. Pair your keyboard and mouse (if using them) to your device
    • You can do this using Bluetooth, or via the USB ports on your DeX Station or DeX Pad 
  3. Connect your monitor 
    • If using a DeX Station or DeX Pad, connect the ends of the HDMI or USB Type-C cable to the ports on the dock and the monitor
    • If using just a monitor, connect the HDMI adaptor or USB Type-C cable
  4. Connect your device
    • Insert your phone into your DeX Station or DeX Pad
    • If using a monitor, connect your mobile device to the HDMI adaptor or USB Type-C cable

Samsung DeX for tablet:

Connect your tablet to an external monitor using the instructions above, or simply launch DeX on its own.

  3. Swipe down from the top of the screen to reveal the Quick Settings panel and tap the Settings icon

    • You can also use your S Pen to interact with the display


Samsung DeX for PC or Mac:

With Samsung DeX for your computer, you can use compatible apps on the larger screen, make use of the keyboard and mouse and easily drag files between devices.

    • Samsung DeX for PC (please note: automatic download)
    • Samsung DeX for Mac (please note: automatic download)
  2. Connect your smartphone to your desktop using a compatible USB Type-C cable and launch the Samsung DeX app on your desktop computer

I actually use Samsung DeX and Samsung Notes to make notes of meetings while working at home :smiling-face: It works great!


While in the field I will also make quick notes  that I can easily access when I'm back in the office by connecting my phone to my laptop to finalize any required administration in the systems :smiling-face: 


Administration might be a part of the job but if I can make it less of a hassle, I will of course do that :winking-face:
