Hi,
I have a nvidia shield k1 with Android 7 and DJI Go4 in OTG. The application  is working fine (no freeze, etc.) except that several parameters are not displayed during my Spark flight: speed, altitude, distance and battery gauge.
Is anybody expereincing these issues ?  Thank you.
Jerome

I forgot to say: I fly with OTG USB cable. Also, the issue was exactly the same when I downgraded to Android 6.
