Can anyone explain why djigo app crashes usually about midflight on just about every flight?  My first 20 or so flights it never happened now it's very frequent.  If I was ever in attitude mode it could cause a flyaway.  Please any tips would be appreciated.  I use a Nvidia shield.

Did you install android 7  on the tablet  ? If so thats the reason. I had to install Litchi till there is a fix .

Yes I did install Android 7.  Can you go back?

There is a way to go back ,kind of complicated i think but you can just do a search iam trying  to understand it myself.

Does anyone have instructions for putting Android v5 back on the Nvidia Shield K1, mine is also crashing every flight

Same old same old.
Shield K1 here also.

Latest version of DJI Go and a P4. App hard locks with the last image it videoed seized on the screen. Thankfully still have control and can hit the RTH.

Latest firmware, latest everything. Tried USB debugging on, tried USB debugging off. Tried Caching on, tried Caching off. Nothing seems to work. Still on Marshmallow.

Had to buy Litchi, glad I did but I shouldn't have been 'forced' into it!

Here are instructions to downgrade from Nougat to Marshmallow.
As everyone says with Marshmallow it works fine you might want to consider this instead of Lollipop:
