Samsung Galaxy S21 now supports DeX wirelessly on PC

Last year, Samsung said that its Galaxy Note 20 will have wireless DeX support with the arrival of One UI 2.5. Of course, that was good news for those who wanted to use a bigger screen to work with their mobile phone. Unfortunately, however, it has only worked with various televisions and monitors and not really with PCs. Now it seems they are rolling out DeX support on computers with One UI 3.1. But it looks like it will only work with the Galaxy S21 for now.

The people of Android Police shared that they can now wirelessly connect their Galaxy S21 device to their PC via the DeX client. But there are still some caveats, but hopefully Samsung is working on that too. For one thing, if you’re using the Link to Windows app on your computer, you’ll have to turn it off if you want to use DeX. After updating to the latest version, you will need to tap on the DeX shortcut on your phone and then choose DeX on PC.

The DeX experience on your PC is limited to 1080p in wireless mode and appears to be better than your TV connection. There is still minimal input lag, but it’s not as bad as lag on the TV. It’s good enough for opening files or watching a presentation, but if you plan on watching a video or playing a game, you might want to try some other connection as latency can frustrate you.

The other caveat is that the S Pen support doesn’t seem to work as expected. When you open Samsung Notes and go to drawing mode, you will have to use the mouse on your PC as the S Pen will not work. This is sad because the Galaxy S21 is the first in the flagship S series to support the S Pen, which was previously the domain of the Note series. Hopefully that can be remedied in future One UI updates as it would be nice to see your S Pen drawing on your PC screen.

DeX wireless support on PC seems to be available only for the Galaxy S21. There is no news for now if it will also be available for other devices that will also receive the One UI 3.1 update.
