Can someone examine the attached flight logs and explain to me why the flight mode changed from GPS to ATTI right after takeoff. Everything was GPS good after starting motors, ascended a few feet and voice command said ATTI Mode engaged. I always go into hover from takeoff and wait 15 seconds or so just to be sure all good. First time it did this. I wasn't ready for this and did surprise me as it was a bit windy. Landed ok but a little nerve racking when not expecting it.
Will have to page down to see all data. Thank you.

As weird as it sounds, every time this has happened to me I hadn't rebooted my phone in a while.  I think it's a bug/glitch in the software somehow.  Might have something to do with the tendency of DJI Go to remain running invisibly in the background even though I thought I ended the app with the Android back button.

I don't think I've had the ATTI problem one time when I had rebooted my phone before the flight.

I have the similar problem with Inspire,

I turn on and off my tablet and remote control between flight, so DJ app is always fresh boot.

Take off and randomly some GPS signal lost in the middle of a flight,
No wind, no interference (I'm about 150 m high)

No idea as well.
