My new Galaxy S22 ultra with Samsung Dex is not connecting to Windows PC using USB cable. The only option available is Wireless to PC. My Windows PC recognizes and opens my Galaxy S22 ultra via USB, but Samsung DEX only activates using the  Wireless to PC option (Wireless WiFi is automatically activated and the USB cable becomes  unnecessary). I want to use the USB cable option because I don't have WiFi when I leave my house. Why doesn't the USB cable option for Samsung DEX work on my Galaxy S22 ultra???

I have the latest DEX for Windows PC version installed..

Has anybody tried this yet?

The USB cable connection option to Windows PC  for Samsung DEX is not available  as a set up option on my new Galaxy S22 ultra. Only the Wireless connection option works.

I always fully update everything on all devices so I don't know if that is a problem. I use the USB cable to connect my ultra to windows 11 with the windows 10 dex app on it. It works.

Others mentioned USB/WiFi issues with dex on s22. Try leaving wifi on (just regular wifi enabled not dex wifi connection), open the app on PC, and connect your phone via USB.

Hi Samsung Support,

On my old Note 9, I was able to share WiFi via Hotspot and use USB to run DEX over USB-c to a Portable Monitor. This is no longer possible with your flagship phone as it seems DEX requires WiFi and I must turn off Hotspot. This totally defeats the purpose for me upgrading to this phone as I require this phone to share WiFI while I use a second screen via USB.

Why can older Galaxy's use Dex via USB/HDMI while sharing WiFi and your newest flagship phone with more processing power cannot do the same?

To those in the community, please vote up this post if this is an issue for you.

Hoping this can be resolved via software update very soon.

Many thanks.

Are using using a direct connection between phone and screen to USB-C to USB-C cable?

This configuration doesn't work on my side.

So I tried a few cables/docks I have and noticed this...

Straight usb-c to hdmi cable works 100% of the time.

Docks will pass through power need the power plugged in AND it needs to be a decent power supply that needs to be plugged in before plugging in the dock. Example... I tried a raspberry pi 3 power supply with a micro-USB to USB adapter and reliability was bad... Sometimes I'll have video, other times I wouldn't.
