Samsung DeX is a feature included on some high-end Samsung handheld devices that enables users to extend their device into a desktop-like experience by connecting a keyboard, mouse, and monitor.[1][2] The name "DeX" is a contraction of "Desktop eXperience".

Samsung first included the DeX feature on Samsung's Galaxy S8 and S8+ smartphones, and has continued to support the feature on all of its latest flagship smartphones, including the Galaxy S9, S10, S20, S21, Note8, Note9 and Note10 series and Note20 series. The Galaxy A90 5G is the first Galaxy A phone with DeX support.[3] It has also been introduced on several high-end tablets, including the Galaxy Tab S4, S5e, Tab S6, Tab S6 Lite, Tab S7 FE, Tab S7 and S7+.


In 2017, the original version of DeX was released, which required the use of a proprietary docking accessory called the DeX Station. This provided a USB-C port, ethernet, HDMI 2.0 output and two USB 2.0 ports.[4]

In August 2018 with the launch of the Note 9, Samsung introduced the DeX HDMI adapter (USB-C to female HDMI), DeX cable (USB-C to male HDMI) and DeX multiport adapter, which whilst still proprietary and containing active electronics,[citation needed] eliminated the need for the previous docking accessories.[5] This design enabled the cell phone to lay flat and function as a touchpad or even continue being used as a phone in its usual fashion whilst being connected to a display and with DeX operating.[6]

Since 2019, with the Note 10 and Galaxy Fold, DeX can now be launched via a direct cable connection to a physical computer using the existing provided charging cable or any similar off-the-shelf USB-C cable with data transfer, eliminating the need for any proprietary docking accessories.[7]

DeX has also been used in the public safety setting to replace in-vehicle laptops.[8]

Samsung also announced "Linux on Galaxy" (since renamed to "Linux on DeX") which allows use of a compatible Linux distribution rather than the default Android OS giving full personal computer capabilities.[9][10][11]

The DeX Desktop can also be accessed with a downloadable app for Windows and macOS or through third party accessories like the Melopow Dock.[citation needed] Users are able to connect to their mobile devices with a USB Cable.

Samsung DeX devices can be managed by Samsung Knox (3.3 and higher) to allow or restrict access using the Knox platform for added control and security.[12][13]

In October 2019 Samsung announced that Linux on DeX will not be available for Android 10 and warned users that after upgrade to Android 10 they will not be able to downgrade back, permanently losing the ability to use full Linux applications.[14]
