- Attach the included power adapter to the Cube dock. The blue LED should turn on
- Connect the included USB-C cable to the USB-C port on the front of the Cube dock. Then, connect the other end of the USB-C cable to the DeX-compatible Samsung phone
- Connect any desired peripherals to the Cube dock (HDMI monitor, USB keyboard, mouse, flashdrive, Ethernet, etc.)
- Allow a moment for DeX mode to load
Please note that DeX is a Samsung feature, and is driven through the connected smartphone — not the Phone Cube. The Phone Cube provides access to the DeX experience by displaying to an external monitor, but doesn’t directly control any of the DeX functions. If you’re running into any issues with DeX or have any questions, please refer to the Samsung DeX FAQ.
