I'm having Samsung A50 too.
I have a problem to connect the phone with Gopro hero 6 through Wifi.
I had already tried everything and even to reset all options and connections on the phone and gopro but connection could not be established.
Gopro is working properly with other phones from Samsung and other manufactures.
Both devices are updated to the latest firmware and software versions.
I have found solution!!!
I sold the samsung a50 and bought Xiaomi phone.
Now i don't have problem using my Gopro on my summer vacation.
Besides connectivity issues now i can clearly hear what other people are talking on phone (bad call quality A50).
Thank you samsung for your great technical support!
