Had a fly-away crash with my Phantom 4. I sent it to DJI for evaluation of the logs and warranty repair.
Loved the Phantom, but this will be the last DJI product I ever buy with this response.
Count me as another one who will not buy another DJI product. This and other cases where they have said a "crash" was not covered because of using 3rd party apps, etc. has convinced me they will do anything to get out of warranty repair/replacement of their defective parts. That plus the difficulty of consumer repairs to the Phantoms and the high cost of parts has driven me to buy or build a multicopter with commonly available parts which can do all or most of the things the Phantom 3 & 4 can do at a cost less than half of what the Phantom 4 purchase price. I'm not including the cost of a 4K GoPro in that but even then it would be much less and enable rapid repairs of crashed aircraft or defective parts.
