Looking for advice. Since the last firmware update, I've been experiencing issues with signal interference. The five bar signal will drop to three within 40M, begin flashing. It drops to zero at ~150M from the controller. It appears to do this regardless of location. I had no issues before with range.

I've tried iOS, and Android phones, Airplane mode/not. Nothing makes a difference. My Phantom 3 has no similar issues in these locations. I've tried fireware rollback and reinstall, and on DJI's advice calibrated the IMU, relinked the RC and calibrated the compass. Is this unit just defective? What else could I try?

Have you tried other locations?

I been reading this is a common issue with the new firmware

I have tried multiple locations. No difference

Is there any chance the antennas have been damaged in some way? Are you now using some attachment that may be partially blocking the antennas?

I've got the same problem where the signal drops away about 30m distance and only 20m in altitude. I will see if the new app update fixes it at the end of this week.
