I bought HDTV capture Type-c dongle, which can display HDMI signal to Andoird devices screen but APP installation is needed, from amazon. It can support Android Device. By the way, I tested on my Honor V20 that is supported and Samsung Tab S7 show nothing.
I google that S7 should support OTG. Why Honor V20 can support but Samsung Tab S7 cannot support?
Which APP can support my dongle? Or, I set what config to enable it
