Samsung DeX (stylized as SΛMSUNG 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".
For technical specifications, Samsung DeX requires hardware such as USB 3.1 transfer specification, USB-C port with DisplayPort Alternate Mode support to be present on a mobile device.[3] Samsung first included the DeX feature on the Galaxy S8, and has continued to support the feature on most of their high-end smartphones, including the Galaxy S, Note and Z Fold lines. The Galaxy A90 5G is the first Galaxy A phone with DeX support.[4] The feature is also available on many Galaxy Tab S models, from Galaxy Tab S4 onwards.
