I would like to try some 3rd party software to fly the spark but one thing is troubling me.

What happens when the spark loses IMU or GPS while using Litchi or Autopilot?
Both depend on GPS heavily to do what they do so I assume that if spark goes into ATTI mode those softwares will not be able to continue flying the drone. But, will you still have contro to fly it manually?  
Anybody out there have experiance with Litchi or Autopilot when the spark loses its mind?

It will be the same as flying with dji go, yes you will have control in Atti mode, if you loose radio control your aircraft will RTH same as dji go .

As far as warranty goes if you crash as a result of using third party apps your warranty is null and void, if you crash as a result of malfunction then your warranty will cover you.

Hi, Louis. I would not recommend you use the third party app as it is not tested and unstable. Please use DJI GO 4 instead. Thanks for your support.

What’s the idea of https://developer.dji.com/mobile-sdk/ while scaring customers away from using 3rd part apps?

There's software that overclocks your GPU right? But you can't rely on warranty when it's getting fried because it's overclocked, should they then remove the ability to use software to overclock it?

The SDK is there to give customers the opportunity to write custom software for specific use cases. DJI provides a nice basis but they sure can't control and make sure the quality of the software. So not be able to rely on the warranty when using "unofficial" software is perfectly normal.

If you loose your IMU it's quite simple... whatever the control software, you will probably loose your drone because it will not be able to sense the "vertical" anymore...
It will quickly end up "upside down", then down only and then in smaller pieces...

...which is not stable, either.

Hi Elektra,

There is no point in justifying use of DJI SPARK software when the latest versions are all having major trouble )

Sorry about the misunderstanding. Your DJI GO 4 crash many times, right? Please provide the crash log of app. Here is the path: mobile device/SD card/DJI/dji.pilot/LOG/CRASH. Thanks for your help.

I dont have a crash log !!  Also My SPARK hasn't crashed  since the last 4 months....
