Maybe this is a better place to post this. I would like to close this off in my mind. Basically my Phantom 4 has flown flawlessly for a year. I kept the old firmware since fall of 2016 because of the issues I saw with other people, but my iPAD mini 4 started updating the DJI Go4 application (I had accidentally set the iPAD to auto update). I did one test flight and it flew great. I took the drone to Fiji and flew it out over a bay with no issues for about 5-10 minutes. It disconnected itself about 260M out and about 58M high. There were no obstructions and no wind drafts. I'm guessing it was either a catastrophic failure or something to do with the DJI Go update. Here is the link to the thread and log file. Any insights would be appreciated.
