Was flying at a location and had no issues with the first battery...landed the bird and took off with the second battery and started to lose control of the bird. Was able to get it back but was a very scary flight. Healthy drones info is below - thanks for your feed back. Hoping to figure out what went wrong and how to avoid being in this situation again.

HealthyDrones gives only a brief summary and very little data.
You'll see a lot more if you go to https://www.phantomhelp.com/LogViewer/Upload/
Follow the instructions to upload your flight record.

The issue is most likely compass related with your Phantom switching to atti because of compass errors due to where you launched and/or calibrated.
What is that place where you started from?

We have seen a sudden spike in reports of P3s rapidly switching between ATTI and GPS modes often combined with an increase in reported compass errors. If you don't mind, would you please let us know exactly which versions of FW you have on your AC and your RC as well as which version of the app? Please just don't say "latest" since that leads to guessing. Since compass issues are so serious, we'd like to be able to find something common in all of these sudden reports. Thanks.
