Samsung DeX is a feature that lets you use your Galaxy phone or tablet like a desktop computer by connecting it to a monitor, TV, or PC.
Most of us carry powerful phones in our pockets, but we rarely use them to their full potential. If you’re someone who works on the go or wants to cut down on the number of devices you carry, Samsung DeX might be exactly what you need.
I’ve been testing it out for a while, and here’s what I learned about this app. And if you’re using DeX for work, it’s worth setting up Samsung Pass too.
