I'm not interested in those. I used to have a Moba controller but I like the PS4 controller better and they did work just fine. I think Samsung stopped supporting it just like the gear VR won't work anymore. My ssd won't even work when plugged in anymore.
That's kind of sucky to have that issue on a newer device! I wonder if you'd get the same outcome with a USB C to USB A adapter with an 8bitdo adapter plugged in? When I use my PS4 controller on my Nintendo Switch it works flawlessly so maybe the 8bitdo would help map the buttons correctly. Meh, who knows, sorry I can't come up with an easier possible fix.
