It's easy to forget that today's ordinary smart devices are essentially portable supercomputers. Your smartphone is thousands of times more powerful than the earliest computer model. Still, desktops and laptops have always offered an experience that phones couldn't. Until recently, at least. Samsung DeX has helped Samsung lead the charge for turning smartphones into desktop computers that can do it all.


DeX is a tool that promises mobile-powered desktop computing. The feature works with most of the best Samsung phones released since 2017, as well as most Galaxy tablets. If you have a Samsung smart device and the right type of monitor, you might not need to look for that new computer after all.

What you can do with Samsung DeX

Samsung DeX offers a desktop computer experience that you can use in a lot of the same ways as a standard computer. You can attend work conferences, spend hours gaming, or tinker with creative projects. If you want, you can use your phone on the side while it powers DeX. Think of it like a computer that's powered by your Samsung device. As long as whatever you do is supported by Android, you should be good to go.
