Samsung DeX now works wirelessly on PCs, if you have a Galaxy S21

When Samsung announced that DeX would go wireless in One UI 2.5, which was introduced on the Note20, I was excited. Up to that point, I had barely touched the app due to the requirement to connect the phone to my PC. Unfortunately, wireless DeX only worked with compatible TVs and monitors, leaving most computers in the cold. Now with One UI 3.1 on the Galaxy S21, it has finally changed.

The first thing you need to do to get started with wireless connectivity is to update to the latest version of the DeX client on your PC. Then press the DeX shortcut in quick settings on your phone and select DeX on PC. Then find the desired device from the list and connect. At this point you will get a connection request on the PC itself ̵

1; it is worth mentioning that this does not work if you have connected to Windows connected, so you need to turn it off before opening DeX.

When everything is connected, you get the same DeX experience you are used to, although it will be limited to 1080p in wireless mode. When I tried this with my TV, everything was lagged and strained – on the PC, however, it was not the case. The entry delay is minimal, but I still do not want to play a game in this mode; The cable is still the way to go for it. But if you want to access your files or fire up a presentation stored on your phone, this should be fine.

Unfortunately, S Pen support does not work as expected. Your phone can still be used normally when connected to a PC like this, and it’s great on the one hand, as I can do my job in DeX while browsing social media on my phone. But if you open Samsung Notes and enter drawing mode on your PC, it uses the mouse – you can not grab the phone and start drawing with the S-Pen. This seems like a missed opportunity, especially now that the S Pen has reached the S-Series.

Currently you need a Galaxy S21 to try this. We tested this on our Tab S7 + with One UI 3.1 installed, but the feature seems to be missing. I hope it eventually changes, but for now it seems to be device specific.
