Ryze (DJI) obviously collaborated with Gamesir, re: the T1d, to coerce people into thinking that was the best/only controller.I have no idea why the official app doesnt work, seems ridiculous to me but there you go.
Even if you don't have an Xbox controller, Tellofpv is far superior to the OEM app.
Any Samsung galaxy s7 series or above.
How did you connect it up??..
