Last Update Date : Sep 12. 2018

Samsung DeX allows you to use your smartphone like a computer by connecting your mobile device to an external display, such as a TV or monitor.

Please note: Use only official Samsung DeX supported accessories to avoid performance problems and malfunctions due to third party applications.

You can connect your smartphone to an external display in three ways.
