I had my P4 for about 3 months, the gimbal was never level no matter how many calibrations I did, it had issues connecting to the app and would quit various times while flying and I kept getting an ESC error. I contacted DJI and they told me to send it in for repair. After waiting 2 months I finally got my P4 back problem is…. IT IS NOT MY DRONE. It has a different serial number and is missing 6 screws from the bottom panel. I contacted DJI again and Richard from DJI support said he would build a case for me to get a new one and to wait for the email. They gave me another shipping label and want me to send it in again for repair. Anyone else have a problem like this? What should I expect.
