One UI 3.1 Brings Wireless DeX Support on PC to More Galaxy Phones


A few weeks ago, it was discovered that the Galaxy S1 series featured wireless support for DeX on PC. Turns out, you can stream DeX wirelessly to a PC that is compatible with the latest One UI 3.1 update, which means more Galaxy devices support the feature.

Reddit user Ahmed_Momen22 posted a screenshot on Reddit revealing support for the feature in One UI 3.1 on his unlocked Galaxy S20 Ultra.

“Get a powerful desktop experience from your phone,” says the image. “Stream DeX wirelessly to a compatible TV or PC, or connect your phone with a cable to a monitor, TV or PC.”

Samsung Wireless DeX One UI 3.1

If you’re unfamiliar, DeX is Samsung’s desktop mode software that allows you to turn your Galaxy S or Tab device into a laptop PC, so you can be more productive on a bigger screen. Can run on the device (on Tab series devices), on an external monitor / TV (either wirelessly using Miracast or connected with a USB-C to HDMI adapter) or as a windowed application on a Windows PC / macOS.

To run the experience on Windows 10 / macOS, you need to download Samsung’s DeX PC software. Previously, you could only run DeX for PC with a wired connection between your Galaxy device and your PC. However, the latest update in One UI 3.1 apparently supports wireless running of DeX for PC, as long as your devices are on the same wireless network.

As we explained earlier, the process of starting DeX wirelessly on a PC is straightforward. Simply lower the notification shade and tap the corresponding icon to start searching for a PC that is on the same network and has DeX PC software installed. After that, just go online.

DeX has always been a great way to expand the capabilities of your Galaxy device. Taking the experience wirelessly makes it even smoother. If you haven’t given the feature a chance yet, now might be the time to do so.
