Samsung rolled out the One UI 3.0 to its latest flagship devices in the last quarter of 2020. One UI 3.0 brings a lot of useful features including performance and power optimization. Recently, they roll out One UI 3.1 update that brought DeX wireless support on PC to its Galaxy flagship device. This feature allows users to cast the DeX experience wirelessly from their Galaxy devices to compatible PCs.
DeX is Samsung’s desktop-mode software that allows users to convert their Galaxy S or Tab device into a portable PC. Formerly, this feature only works with a wired connection between your Galaxy device and PC. But in the latest One UI 3.1 update, enables a wireless DeX. It is first reported by Galaxy flagship user in Reddit posting a screenshot of the changelog of the One UI 3.1;

The changelog indicates “Cast DeX wirelessly to a compatible TV or PC”, however you can still choose to use DeX wired.
Anyway, this latest feature now available on all recent Galaxy flagship devices running One UI 3.1. This starts with the Galaxy S10 series. It is available on the S10e, S10, S10+, Note 10, Note 10+, S20, S20+, Galaxy S20 Ultra, Galaxy S20 FE, Galaxy Note 20, Galaxy Note 20 Ultra, Galaxy Fold, Galaxy Z Flip, Galaxy Z Flip 5G, and the Galaxy Z Fold 2.
Lastly, a report by Android Police says that this wireless feature output on a TV is laggy and glitchy. So, the best option as of the moment is via wired. Also, this wireless mode experience is limited to 1080p. In PCs, we suggest first updating the latest version of the DeX client.
