I have Xiaomi mi mix3 android 10.
Has a USB Type C, it is possible to use FPV.
Today I checked with Huawei Y6, android 9, USB micro.
Files (* .json) are received without problems. But there is no way to use FPV (USB micro).
P.S. To return to Xiaomi, I had to do a global reset of the remote control and all the batteries.
