I use lightbreidge 2 and A2, gopro4, Gallaxy Tap S2 pad.
I changed flight mode toggle in transmitter, then changed A2 LED blue or yellow, red.
But did not changed flight mode from manual mode on Dji Go app with S2 tap.

when I use Ipad 2, can change flight mode to Atti or P-GPS on Dji go app.

It seems that Gallaxy Tap S2 pad is not completely compatible with DJI GO App. Please use our recommended mobile device for better performance.
