Anyone had these messages before?

I was flying spark today in open firld , no interference sources and no no fly zone. This suddenly happened , gps failure , it went into atti mode and start moving to all sides. Fortunately i could land the spark. Just to be sure i did the compass calibration and afterwards it flew fine.
Yesterday i did the new firmware update.

Also it says weak gps signal. Thats strange , as i had connection to 17 satellites

Could you please provide the flight data and the black box data of this flight? I'd like to forward it to our engineers to check what happened. Please upload both files to Dropbox and post the link here, thanks.

If it is possible, could you please export all of the flight data and black box data, then upload all of them to Dropbox,  I am sorry to say that I didn't see the data in the link which you've provided. Please also sync the flight records on the APP, then provide me with your DJI account email and the date this occurred. Besides, should you have any further questions, please click on the "reply", so I can get a reminder.

Hi diana
Its been a few weeks now when i reported the error , hundreds and maybe thousands of spark owners had also. Do you have nees from the engineers? I think it's about time that all spark users will get an answer or better a solution before some damage or harm is done by a crashing spark. Please update us and please let the engineers know again and hurry up a bit with this
