The Galaxy S21 series can now be used wirelessly with Samsung's DeX platform on PCs, giving s seamless and untethered access between their devices. It was already possible to use DeX on certain Galaxy devices wirelessly with compatible Smart TVs, which s can then use as an additional display for work, multitasking, or watching video content from their device. This additional wireless improves the integration between Galaxy and other devices.
Samsung DeX was launched in 2017 but initially required a special docking accessory for use. As with some other tools, it provides a way to easily transfer data between smartphones and computers, to view content from a device on a second display, or to cast content to a Smart TV, but it can also be used with monitors (including Samsung's Smart Monitor) to power a PC-like experience. The gradual evolution of DeX has not only given it more features but made its interoperability with other devices more seamless.
As reported by Android Police, that now means a wireless connection between Galaxy S21 devices — and specifically those running Samsung's One UI 3.1 Android skin — and a PC. The functionality is said to be limited to 1080p resolution in wireless mode and S Pen is apparently not fully up to scratch as yet. Nonetheless, the report states that it is possible to use an S21 normally while DeX is up and running on a PC, allowing both devices to be used simultaneously if needed.
Wirelessly Connecting A Galaxy S21 & PC With DeX
Currently, running DeX wirelessly with a PC requires a Galaxy S21, S21+, or S21 Ultra, although Samsung can be expected to expand that going forward. s should first check that they have the most up-to-date versions of DeX installed on both their phone and PC and that their two devices are connected to the same Wi-Fi network. Assuming that's all the case, they can open the DeX mobile app and select the 'DeX on PC' option. This should provide a list of devices to which they can connect. After choosing the relevant PC, a prompt will appear on the PC that will enable the wireless connection once accepted.
With their Galaxy S21 smartphone and PC connected, s will now be able to transfer data and make use of certain functions across the devices. Files, photos, and videos can be moved between the two by simply dragging and dropping, while it's also possible to access messages and take calls on the PC.
