I had this come up in my view this afternoon when I went started up my phantom 4 Pro. It’s not been in a crash, (knock on wood), and I’ve really been careful to handle it with extra care. The only thing I’ve done recently was the camera calibration on the DJI assistant last night. I did check it out after the calibration finished and everything was fine. It hadn’t been out of the case and that when I noticed this. Has anyone had similar issues or any suggestions?
