How DeX Works

Initially, to use the Samsung Dex feature, you would need a DeX docking device to connect your phone. Now, you need an HDMI adapter, a DeX cable or multi-port adapter, a display with an HDMI input, a mouse & keyboard, and a DeX capable smartphone or tablet. The mouse and keyboard you need should be preferably Bluetooth but you can as well opt to use the ones with cables and connect them to the multi-port adaptor.

First of all, connect your mobile device to your display using the HDMI adapter, a DeX cable, or a multi-port adapter. Samsung DeX should then launch automatically, giving you access to all your mobile apps and content. Next, you need to connect your mouse and keyboard via Bluetooth. If you’d prefer, you can use a USB keyboard and mouse with a multi-port adapter.

Once you’ve got your mouse and keyboard connected you can enjoy an intuitive desktop experience. You can use your smartphone as a touchpad by simply swiping down from the top of the screen to open the notifications panel and then taping the option to use your phone as a touchpad. Afterward, proceed to use your finger or the S-Pen for navigation.

To scroll through pages, simply swipe up or down. Tap your smartphone – which is now a touchpad – once to open apps or select something just like you would with a single left-click on a mouse. Tap with two fingers to open the options menu – similar to a right-click on a mouse. To zoom a figure/subject, simply pinch your fingers in or out.

Smartphone manufacturers are doing everything possible to enable you to use your phone more like a computer. The DeX feature is a testament to this. Does your Samsung phone have support for DeX? How do you find the experience so far? Share with us in the comments section.
