Samsung has been supporting DeX on Windows PCs since 2019 with the Galaxy Note 10 series. This feature allows the phone's content to be displayed on a Windows computer and makes it easier to transfer data between two devices. Samsung recently confirmed through its official website that it will end this support on devices using One UI 7 based on Android 15.
DeX users on PCs are encouraged to move to the Link to Windows application, which offers the same user experience, but without the desktop-like interface. Support on macOS computers has been discontinued since 2021.
It should be emphasized that only DeX on PCs is being discontinued. The Samsung DeX feature, both wired and wireless, will still continue on select Galaxy smartphones and tablets. On Samsung's latest tablets, the DeX activation button is still included on the physical keyboard sold.
