Why is the latest and greatest S25 Ultra not support for Dex for PC?

[xframe]

Hi,

I do use Samsung Dex frequently and I got my S23 Ultra and S25 Ultra. How come my S23 Ultra can use Dex for PC but my S25 Ultra cannot use Dex for PC? It says not supported for One UI 7 and above.

Please enlighten me!

Hi @xframe,

DeX for PC will not be supported for One UI 7 and later as per screenshot, do connect using Link to Windows feature instead, you can find more info here:

Hope this helps!

It sounds like Samsung has changed the DeX compatibility for One UI 7 and above, possibly limiting its use on certain devices or with specific PC versions. A few things you can check:

1. Software Version – Ensure your S25 Ultra is fully updated. Samsung might release a fix in future updates.

2. DeX App Version – If you're using DeX for PC, try updating or reinstalling the DeX software on your computer.

3. USB Cable & Connection Mode – Use a high-quality USB-C cable and check if the phone is set to "File Transfer" mode when connected.

4. Samsung Support – Since this seems like a policy change, reaching out to Samsung Support may clarify if DeX for PC is permanently discontinued for One UI 7+ or if a future update will restore it.

Let me know if you want help troubleshooting further!
