When I go in the "watch me" mode of follow me, I can stand still and after a few seconds the drone will start rotating but the scene on the phone will stay the same for about 30 seconds or more then it will start showing the rotation. As long as I stay in that mode the camera signal has a terrible delay and of course follow me doesn't work. All other times the delay is minimum. Follow me in the GPS mode works sometimes and sometimes not. Sometimes I get the "phone GPS signal is weak". LG K20 android phone. Is there some way to get a stronger phone GPS signal?
