Dex issues One ui 8

[Streki]

Hi, my S25 ultra was update yesterday. Today I try use my docking station with USB-S and HDMI port. But not working in DEX mode. Docking only mirror my screen but DEX not starting. Why? I use 3x dos king stations from Lenovo, itec and other and now not working? Why? Samsung delete this support? Its not fun. I need working on this. Thanks for help.

Has anyone else had issues using Samsung Dex after the One UI 8 update? 

Also, my screen on my phone freezes while and after I disconnect.

DeX working fine for me.

Have you followed the best practices after an update guide? Clearing device cache via recovery mode in particular.

If the issue persists, send an error report to Samsung via the support tab in this app.

Same problem here. S25 Ultra, 8.0 update. DEX keeps crashing. Reboot doesn't help. Clear cache doesn't help.

I will like to remove the updated. I need my dex to work on my pc. The upgrade kills phone productivity. To be honest, this upgrade looks like a retrogression. Dex on pc was the most innovative app samsung had. In a competitive market with the rise of Chinese phones, I don't know whether this was a smart move.

Downgrading is not officially available. Unofficial methods are not recommended as you run the risk of bricking your device.

Whether you read the TOS or not, you agreed to software updates when you first set up the device.

While DeX for Windows has been discontinued, both DeX and Link to Windows are still operational, retaining a large portion of the functionality.

If you dislike these changes, you can send feedback to Samsung via the Support tab in this app.

Yep. I'm having the same issue as well.

What fixed Dex for me was clearing One UI Home data and cache. Hope this helps someone else!
