Phantom 3S RTH messages I have never seen

[Kmb]

Check out the attached flight logs Look at the end of the first log when signal was lost. I got a RTH cruise and backing up to avoid obstacles message. Hmmmm. On a PS3? Then the DJI GO app closed by itself. I reopened it and a new flight log was created. It started with a RTH cruise message. Any thoughts?

Interesting. The same unusual question twice in one day. To me that is not a coincidence.
