How to Install Linux on Dex in Galaxy Note 9 and Galaxy Tab S4 (In-depth)

Samsung had announced the Samsung Dex along with the Samsung Galaxy S8 and S8+; The DeX is – a clever contraction of “desktop experience” that can be made using a compatible Samsung Smartphone. The Samsung Dex is an Android equivalent to the Microsoft’s Display Dock that was launched along with the Windows 10 on mobile, allowing the users to use the power of your phone to run a desktop computing environment efficiently, Samsung has been claiming that it is enterprise-ready, offering a way of using Samsung’s smartphone as the brains behind your desktop computer.

The Samsung DeX has an amazing and intelligent design as it folds out from its flattened shape to form a dock, with the backrest changing into a fan for cooling the smartphone, and has a USB Type-C in the base for power and data transfer.

Ports on Samsung DeX:

  • HDMI
  • Ethernet
  • USB Type-C

With this being on the DeX, the users can set it up as a workstation for their office work, with a Bluetooth mouse and keyboard connected to a monitor via an HDMI cable. The Ethernet connection port also means that the uses won’t have to rely on the phone’s Wi-Fi for internet connections. It is a good looking thing with a clever solution, a lot better than the Microsoft Display Dock that resulted in a lot of wires. The main highlight of this being that Samsung assures us that it’s plug and play, meaning the users won’t have to do anything to set it up.

Overall Experience of Linux on DeX:

Samsung Dex Ubuntu

The Overall Experience while using Linux on DeX was terrific; I didn’t expect a beta staged app to perform so well while being run on a smartphone’s hardware. Linux was running on a container, which was the part of the DeX ecosystem, and installed on an app on the Samsung Galaxy Note 9 or Galaxy Tab S4. There were so many layers, yet the device performed decently well in our test. There was some intermittent lag, but overall, applications ran quickly and without much latency. Also for who are interested in, it runs Ubuntu 16.04 LTS with Android Security Policy baked in. 


Now that you know how to install and run Linux on Dex let’s check out what you can do with it. Using Linux on dex, you can do some pretty heavy processing stuff including but not limited to –

  • Running and maintaining Git code
  • Creating C/C++/Java projects using any IDE
  • Managing and monitoring your server via the CLI

Now the functionality of Linux on Dex is not limited to these only, the only limitation you have here is your phone’s hardware. Current day flagship smartphone processors might be a powerhouse, but they are no match to a full-fledged chipset. Nonetheless using your imagination and with a bit of Samsung’s help, the applications here are endless. Let us know your thoughts about this in the comment section down below.

  1. Has anyone tried this on a Samsung Galaxy Note 8? The Note 9 is not much different to the Note 8, so I wonder if it would also work.
