suddenly my drone and controller won`t find any gps satellites. on the app it says "compass data is abnormal fly the drone back and recalibrate" i can`t fly it at all. i was flying it yesterday and got a call when i answered the call i guess it disconnected and when i hung up the drone was down no visible damage and it landed on the sand at the beach. it looks like it can down in a normal landing and didn`t crash , landing right side up. i have tried new batteries and recalibrating but nothing works. any ideas? thanks
