I updated the firmware earlier this week because the app asked me to. Without even thinking about it, I shut the drone off, slapped the BIN file on the SD card, and fired the drone back up. After a few seconds, the camera made a sharp turn to the left (about 45 degrees) and then the app showed critical error. The errors read something like:

I was immediately concerned. However, I let the firmware update continue. The camera re-centered itself, the errors disappeared and it completed. Because I'm super paranoid, I shut down the drone, powered it back up, and checked to see if it would begin the firmware update again. It did not. I then checked the log and saw nothing but "success." I then put firmware 1.8 back on the card, attempted to downgrade, and got the same behavior. I downloaded a fresh new copy of 1.9, updated again, and same behavior.
After doing some research, I found out that I shouldn't have left the RC on..... Oops... But even if I shut the RC off and attempt it again, I still get the odd behavior of the camera. Has anyone else experienced this? I have yet to fly it since the update.
