Samsung DeX is an exclusive software feature that promises smartphone-powered desktop computing for those who often find themselves away from their desk setup or PC. It's essentially like using a computer that's powered by your Galaxy phone.

The desktop experience offered by DeX is obviously not a full replacement for your standard computer, but it's good enough to get a lot of things done when you find yourself in a pinch or are on the road without your full machine.

Which Samsung Galaxy devices support DeX?

DeX is a neat feature that is exclusive to Samsung devices, but it's not supported by all models of Galaxy phones or tablets. It's been supported by almost all flagship Galaxy devices since its introduction in 2017 with the Galaxy S8 family, and that includes the new Galaxy Z Fold 6 and Galaxy Tab S10 tablets. However, there are a few exceptions. Here's a list of Samsung Galaxy devices that support DeX:

  • Samsung Galaxy S phones: Galaxy S8, S9, S10, S20, S21, S22, S23 and S24 series
  • Samsung Galaxy Note phones: Galaxy Note 8, Note 9, Note 10, and Note 20 series
  • Samsung foldables: Galaxy Z Fold, Fold 2, Fold 3, Fold 4, Fold 5, and Fold 6
  • Samsung Galaxy tablets: Galaxy Tab S4, S6, S7, S8, and S9 series
  • Samsung Galaxy A-series phones: Galaxy A90 5G

One notable omission here is the Galaxy Z Flip series, which has never supported DeX. While Samsung has finally added display output support for the Galaxy Z Flip 5 & the Galaxy Z Flip 6, they didn't add DeX support to the devices because of temperature concerns.

What's the best way to use Samsung DeX?

It's worth mentioning that there are different ways to set up and use your Galaxy device for Samsung DeX, and it depends on the compatible devices you're bringing in for your setup. All the Galaxy devices mentioned above support DeX using a wired connection.

You can either use a DeX cable (USB-C to HDMI) or pretty much any HDMI dongle or a hub that lets you connect your phone to a monitor or a TV. Galaxy S-series and Note phones can also use a DeX Pad or a DeX Station to establish a connection. Below you'll find a link to buy the type of HDMI adapter I personally use, along with my peripheral of choice for a DeX setup.

    This simple USB-C to HDMI adapter is a great option to consider for DeX. It also has a USB-A and a USB-C port for your peripherals, like a keyboard and mouse.

    This Logitech K380 keyboard and M350 mouse combo is perfect for a portable DeX setup. They're both compatible with a bunch of devices, and neither of them will take up too much space on your desk or in your bag.

  • Portable keyboard with built-in touchpad

    It's not a desktop-level keyboard, but if you want something ultraportable, this iClever keyboard can be folded so it fits anywhere. It still has some spacing between keys and it even has a touchpad built in.

You can also use DeX wirelessly or by connecting your phone to a PC via a USB cable, but they're not supported by the older Galaxy S8, Note 8, or Tab S4 series. I suggest you stop by the Samsung DeX support page to learn more about the DeX compatibility and other requirements based on the device you have and the type of connection you're looking for.
