I am definitely not in love with my new S22 Ultra and have been delaying sending in my Note 10+ trade in as it never gave me any issues. I guess newer is not always better!
The most frustrating problem I have is with using Samsung Dex on my S22 Ultra to broadcast from my phone to my LG TV. I was able to do so with my Note 10+ with no issue. While Samsung Dex connects and the interface appears on the screen. I immediately see a small message that my TV is not optimized for wireless display connection (or something like that). I can navigate to my gallery and select a video to watch. It will start the video for a second or so and then it freezes and shortly after severs the Dex connection. I will sometimes get a message to make sure there's nothing blocking the phone to TV (there isn't). Both the phone on the TV are on the 5GHz band of the router. The TV is a 2020/2021 model- LG OLED65CXPUA. Is there anything I can do to fix this issue?
I ended up factory resetting my LG TV twice as I noticed the apps weren't updating (firmware was up-to-date). It wasn't until I switched the TV back to the 2.4 GHz wireless band that the apps would update. I tried Dex again and it was better but still not what I would consider working. Then I connected my S22 Ultra to the 2.4 GHz wireless band and......Dex works!!! So, so odd given the TV and my phone are both within 10-12 ft of our router. Hopefully this can help someone else!
This is interesting because an existing wifi network is not required to use wireless DeX. I use it while camping all the time without any wifi network.
