My Heading Indicator going in circles and jumping around the Compass Radar at the bottom left of the Vision App Camera Screen. Help! Can someone help me determine what is going on with the Navigation Radar in the Vision App. I'm using an HTC ONE M8 on Android. I calibrated the drone and the compass on my Smartphone. Watch this video and observe the change and behaviour at 1:23 point and then at 4:06 it seems to correct itself... http://youtu.be/Q0qQqGThFys Any ideas what's going on. I know there was a compass issue with my phone model months ago but they fixed it with a firmware update to the phone.
