Abnormal Mavic behavior - Crashed my Mavic

[Perkele]

Hi,

I have owned Mavic about 2 months. I had no other problems but the image is really soft on the other side. I have latest firmware.

So I was flying my mavic yestarday, first battery with no problems.
With second (same battery, charged) battery I didnt have any problems at first. But then I noticed some strange behavior with gimbal (spins wildy around like when calibrating)
When battery reached 30 percent power, I started to land my mavic.

First I was getting message "Mobile CPU overload. Related performance will be affected" multiple times and live feed was getting very choppy. So I press RTH button.. and nothing happened.

I was landing withoud live feed at this point from ~50m to 5m with mavic on my sight.
At this point I noticed that when I push right stick forward, mavic moves sideways, left goes back etc. Controls totally messed up.
Then Mavic stop responding to controller up/down stick.. hovering in the air about 4m height.

I then press emergency stop button and Mavic goes crazy.. shoots full speed at nearest building.

I didnt get any other warnings than CPU Overload. Calibrated compass normally before first flight. No compass errors.

Mavic & camera seems to be ok, all props shattered and some scratches.

Faulty compass or electromagnetic interference? Any ideas?
I hope you understand, english is not my native tongue

Oops sorry about that. Wrong file. This should work: DJI_ASSISTANT_EXPORT_FILE_2017-11-20_18-02-59.DAT

According to the DAT file you were operating it in a hotpoint mission mode, which probably accounts for the stick behavior.

I do not understand how it is even possible that the point of interest mode goes on its own? It does not explain that the controller did not respond to the ascend/descend commands.
understand that Mavic should stop the current fly mode if the stop button is pressed? In my case, Mavic decided to go full speed straight to the wall

What's hotpoint mode?

 

[stressor]

hotpoint mode flys circles around a gps spot (DJI Mobile SDK Documentation). however this doesn't seem to explain the crash.
