You can configure Horizon Client to start automatically when you switch your Android device to DeX desktop mode.

If you added a desktop or application shortcut to the Android home screen, Horizon Client connects to the most recent shortcut after Horizon Client starts. For information about adding shortcuts to the Android home screen, see Add a Desktop or Application Shortcut to the Android Home Screen.

The DeX mode auto launch feature is disabled by default.


Verify that your Android device supports Samsung DeX.


  1. Before you log in to a server, tap the Settings (gear) icon in the upper-right corner of the Horizon Client window.
  2. Tap Display, tap Dex Mode Auto Launch, and select the Dex Mode Auto Launch check box.
    The DeX mode settings are hidden if your device does not support Samsung DeX.
