What is the Samsung DeX? Details on Samsung’s docking hub, including price and apps


Samsung’s DeX asks the question: Can a phone replace a PC? The docking hub lets a user slot-in their Galaxy S8 handset and then uses that very same Android operating system to run a full desktop experience. You’ll need a monitor, keyboard and mouse, plus of course your smartphone, though that’s all you need. 

So will DeX replace your PC? That very much depends on what you use a PC for, but it is certainly a capable device. Samsung are not the first to create a mobile-hybrid desktop. In 2011, for example, Motorola created something pretty similar to the DeX, though the Atrix was hardly met with commercial success. Just because Motorola failed before doesn’t mean you should ignore Samsung’s hybrid – Apple didn’t invent the tablet, but the iPad was the first to go ultra-mainstream.

So what can the DeX do and who should buy one? Here’s a simple breakdown of what you need to know. Also, if it has sold you on buying the Samsung Galaxy S8, check out our full review for the new flagship smartphone right here.    

Samsung DeX: What can it do?

Multitasking has been possible on a smartphone for a few years now, but multitasking tends to still be much easier on a full desktop compared to a small handset. Even bigger smartphones like the iPhone 7 Plus or Galaxy S8 Plus can’t offer the same experience as a desktop on their own, sometimes leaving you longing for a mouse and keyboard. Samsung knows this and with the DeX you can multitask, albeit on the Android operating system – and only with the Galaxy S8 and S8 Plus.

The puck-shaped device comes with the following connections: 

  • USB 2.0 x2
  • HDMI
  • Ethernet
  • USB Type-C

This should be eveything you need to connect the DeX up as a workstation, with a mouse, keyboard and monitor slotted into USB and HDMI ports. The inclusion of an ethernet connection means you can connect to wired internet – useful if the Wi-Fi where you’re working is patchy. 

Slot in your Galaxy S8 and a desktop will appear on your connected monitor. All the PC features you’d expect are there; including the added simplicity of right-clicking, something you just don’t get on a smartphone. Drag-and-Drop plus all your standard keyboard shortcuts are there too, so don’t expect a watered-down experience in that respect.

An apps tray can be accessed in the bottom left corner of the screen, much like a Start tab in Windows. You’ll also have the option to make shortcuts on your desktop – again, much like Windows or iOS. If you get a call while working, a notification will drop down on the right side of the screen. 

Not all apps are compatible, and Samsung is working with developers to increase the range of options, but many of the most popular services can be used with Samsung DeX. This includes all of Microsoft’s Office suite (Word, Excel, Powerpoint and OneNote) as well as Skype. Google’s cloud-based tools, including Drive and Photos, make the cut. As do Adobe’s range of software. Elsewhere there are games, such as The Tribez, and Lineage2 Revolution. Samsung DeX users can also access the Google Play Store to install additional apps and only those available for DeX will appear when using the dock. 

A nice little extra is being able to still use the S8 as a phone even when it’s docked, so you won’t miss important calls just because you are doing some desktop work. You can accept the call via the desktop, meaning you don’t need to undock your phone to have a conversation. If you do want to pick up the phone, simply undock it from the DeX and carry on as normal. 

Samsung DeX: Who should buy it?

The DeX isn’t designed for everyone but it is there to improve general productivity of the Samsung Galaxy S8 by allowing users more flexibility with their work. On a mobile you can work anywhere, but integrating a mobile and desktop office into one can make life much easier. No more carrying around a heavy laptop if all you’re looking to do it reply to Slack messages and browse the web.

Smartphones tend to have many of the apps we need for work, but it can be difficult to complete tasks with the precision you’ll find on a full desktop, be it formatting long work emails or viewing images – sometimes you need a bigger screen and precise controls to get the job done. When it comes down to it, whether the DeX is right for you depends on the kind of work you do. DeX isn’t a super-powered PC by any means – it uses the Galaxy S8’s innards to work – but if you mainly use the Office suite, Google docs, and Slack, it might be a cheaper alternative to investing in a new laptop or home PC. Adobe has also worked to ensure Lightroom Mobile works with a keyboard and mouse. All that said, if you do need to do design-heavy work with tools such as the Adobe suite and Photoshop, this probably isn’t the product for you. 

Samsung DeX: Price and availability  

The Samsung DeX has released alongside the Galaxy S8 and S8 Plus here in the UK. Unfortunately European customers won’t be able to get their hands on a bundle like that found in Asia where they have the S8 Plus with an astonishing 6GB of RAM bundled with the DeX dock. So that means if you want the DeX in the UK you are going to have to buy it separately, which is steep if you’re already paying the full price for a Samsung Galaxy S8 or S8 Plus. The good news is that the Samsung DeX has already dropped in price a bit from some retailers. The RRP is £130 but Amazon UK have been selling it for £120 (or on Amazon US for $140), so keep an eye out for a bargain. If you can’t find t on Amazon then you can obviously pick it up direct from Samsung, but expect to pay the full RRP.

Samsung DeX: What are the specs?

The Samsung DeX is pretty straightforward when it comes to specifications. It doesn’t have many ports, but on the product itself you’ll find an Ethernet port, so no need to count on the S8’s Wi-Fi for your internet connection. Furthermore, you’ll get USB Type-C and USB 2.0 ports. The DeX does charge your smartphone when its docked as you’d expect, there is also the option to use an HDMI to power instead. Although, Samsung is slightly sneaky here asking that you buy that cable separately if you want HDMI charging for the DeX. Nevertheless, the option is there if you want to simply things even further.

The Samsung DeX is minimal apart from the access ports, though there are some nice touches. It has a cooling fan to prevent your mobile from overheating when it operates, so there shouldn’t be an issue with ventilation. The DeX is also very portable weighing just 230g. This is much less that a laptop, and given the Samsung Galaxy S8 is about 200g, you’ll be getting a desktop PC experience to carry round with you for less than half a kilo in weight, not bad.
