Samsung Dex is a pretty amazing technology that turns phone into a full fledged desktop PC. The original device costs about $150 but has some limitations such as not being able to use headphone jack and basically having the phone locked down. A cheaper, and arguably a more functional device can be had for less than $40 with things like the Melopow Doc that leaves the device in a more usable state with full access to the devices ports at a much better price. And while using DeX, make sure to use the fantastic Dex MaX app to add support for fullscreen to all your apps. Happy DeXing!
