I bought an iPad Mini thinking I was buying an iPad mini 4.  When I got it I tried to upgrade the OS from 9.35 something but it said I had the latest version.
Then I tried to download DJI Go 4 and it said it wasn't supported on this device.
I then downloaded DJI Go and it doesn't work for a Spark.

I realized I screwed up so this is just an advisory to double check your research.

Thanks.  I really enjoy this forum.
Been flying Spark since 05/22/2018

Hi. Thank you for the information that you have shared with us today. I will post the recommended mobile device for the DJI Spark for additional reference. Thank you.

Thanx. I’m learning a lot

I misread the ad I ordered from.  I thought I was ordering a mini4 but it was just a mini.
No more support from Apple.  
I'm trying to return to seller.

A 4 GB cash memory tablet is the best for drone apps.

Welcome Mate !

Great info. I am faced with the same situation with an old iPad mini I would like to dedicate to drone piloting.  But now I know the minimum iPad requirements.  I'll look to pick up a used one that meets standards on the internet.
