I'm having problems with Dex by using my Note 20 Ultra and trying to connect to a Q80T (2020) TV. Both are on the 5GHz wifi network and as you can see from the model names both are new (from 2020).
I go into the "Dex on TV or monitor" on my note 20 and it can see the TV ([TV] Samsung Q80T). When I select the TV I click on the "Start now" message that appears on the phone screen and it says "Connecting..." but never connects.
I have also noticed that the TV is not asking me about accepting connection from the phone.
What is going on?
Thanks for helping!
Both are on the same 5.0GHz wifi. I did another test and tried to start a Dex session with a S10+ and it started successfully. Nevertheless, the response was very sluggish and eventually it disconnected after about 20 seconds and I wasn't able to make it connect again.
After trying with the S10+ I tried again with the Note 20 Ultra and it connected successfully. I was able to open the app tray but then it also disconnected and I haven't been able to make it connect again.
It seems like the feature is very buggy. I don't think is the TV. It's a $3,500 TV less than a year old so it shall support the feature, doesn't it?
Also I have all my other devices on ethernet. The only devices on the 5.0GHz wifi are the two phones and the TV so bandwidth is not the problem.
