Samsung‘s DeX was the technology everyone thought you could finally leave your laptop behind and use the processing power of the powerful processor on the smartphone to do more than just basic tasks on the go by connecting the phone to a monitor, TV screen, or computer .
However, the fact that a wired connection was required between the two devices to enable this feature was the biggest downside. But with the Note 20 range, it was Samsung expected to get rid of this limitation by enabling wireless connectivity under DeX.
The folks at AndroidPolice were able to connect the phone to both a computer and a TV and unfortunately reported some bugs as well. As of now, the wireless stream is limited to 1080p, with a noticeable lag and stuttering when the function was tested on the TV.
On the other hand, no lag or lag was seen on a laptop, although the performance is still not up to par when compared to a wired connection. In addition, the use of the S Pen should also be avoided from now on, as DeX does not seem to react to the inputs of the S Pen on the Galaxy S21 Ultra. This is disappointing indeed for the S 21 Ultra users who thought they could sketch with the S Pen on their phone while connected via DeX.
Another limitation reported with DeX functionality is that it cannot coexist with Microsoft’s Link to Windows application. Users who have used Microsoft’s utility may need to turn it off in order to use DeX to connect their Galaxy phone and computer.
