How do I use the Samsung DeX desktop environment?

The Samsung DeX software comes pre-installed on your Galaxy and, when you plug your phone into an external display via an HDMI adapter, transforms your phone into a full desktop environment. You can choose to use a Bluetooth-enabled keyboard and mouse, or you can turn your phone into a trackpad or virtual keyboard. For more information, click here.

Once your phone is connected to an external display, a popup menu will appear on your phone screen. For the complete PC experience, tap "START SAMSUNG DeX." Otherwise, you can tap "SWITCH TO SCREEN MIRRORING" to cast your phone screen to the external display while maintaining control on your phone.

Note: Your Samsung Galaxy does not come with the HDMI-to-USB Type-C cable necessary for connecting your phone to an external display or monitor.
