i have read all over but have not been able to find an answer or figure this out. My 4K acts strange in smart mode. It will not hold position. It constantly drifts away from my position. It is not the geofence I can have the drone 50' in the air and 100' from me switch from angle to smart mode and the drift away starts. Also I can barely get the drone to move toward my position. Angle mode no problems only in smart mode. I have calibrated the compass and the controller. Also smart mode doesn't function correctly on the flight controls, it functions just like it's in angle mode. Any help,would be appreciated.
