I have a camera issue after the recent upgrade that the gimble glitches slowly down as I'm trying to pan downwards, but when I go up its smooth as can be. Never had this problem at all till now.
The other issue is the ultrasonic interference land immediately signal just about 2 out of 5 flights. Never had that issue either till now.
The compass now points 70 degrees off of home point nose direction even after multiple calibrations, imu, stick...etc. it shows that I'm 15 to 20 feet away when in actually I'm right next to the phantom. So to agree or not to agree it comes down to I had no issues till the recent update of 1.2.8 or whatever it is.. and now all this... so dji needs to get on it.
I know the short term fix for you on your issues. It has helped numerous others.
Go in your User Center and click the cloud to sync you flight log files if you save them. If you don't save them, then skip this part.
Next on the device you use to fly with delete the app completely.
Next install the app once again.
Next in MC Settings go in the gimbal section and select the auto calibration.
Next in MC Settings go to RC Control Settings, select RC Calibration, select Calibrate and move the sticks as directed. DO NOT forget to also calibrate the Gimbal Wheel in that same process. The meter graph for this is displayed near the bottom of the two stick images.
Next in MC Settings go to Sensors, select IMU Calibration, select OK after following directions for level area, and begin process. Once finished save process by rebooting the quad.
Next and last process is to calibrate compass and once again save settings by rebooting quad. DONE
The only other thing you probably need is to disable the VPS feature. This is if the quad has not flown properly.
Be sure to come back and update how things turned out for you.
