Hello,

A friend of mine borrowed my drone about three months ago. Since then, the drone hasn't been flying right (i suspect motor damage from some sort of impact). I've been digging into the data and it looks like there may be a way to download data and tell if the drone has been crashed. Does anyone know how far back into the data I can go to investigate? I've probably logged a few hours flying since then. It sounds like the files may be overwritten? I want to try to find out before I fly it again. Any help would be greatly appreciated.

Thanks!

If your friend used your phone or tablet, the flights will still be on it, unless someone has deleted them.
They don't get overwritten.

You can replay the data for any flight in the app or import to a computer for detained analysis.

The DJI Go 4 app should display the flight data for all flights unless someone has deleted some.

I should note that they used their own device for the flights, not mine.
Would I be able to see the detailed information for the flight on a specific day/time from the drone itself? I've flown quite a bit since then, so I wanted to try to locate that specific day/time in enough detail to tell if it had any abnormal activity (even if it was a minor impact?).
Sounds like DJI has data analysis they can do on it, but it doesn't say how far back they can go?

Thanks!

Thanks @DJI Stephen. If I send my drone in for diagnostics, can DJI use the drone's black box to check for a crash from three months ago?

The .txt files will be on the phone/tablet that was used to fly the drone.
The internal data is encrypted and not readable except by DJI.

Yes, so that's my question. If I send it to them, approx. how far back can they go to investigate? I'm reading on some forums that it stores everything from when you first got the drone, but others say it gets overwritten with new data. I'm trying to gauge if mine would reasonably still have the flight data stored on it for dji to use.

Ok, but I don't to pay to ship it in for diagnostics if the data isn't there. Is there a way to know for sure?
