With my smart controller for AIR 2S I am sick of using my iphone and want to get an ipad mini to use with controller.
I ONLY want to use the ipad mini as the screen for the controller and not for anything else at all.  I do not vwanyt it linked up to any other devices, or phone or SMS etc, JUST as a screen via the DJI App.  I will store all pics and vids on another device.  Best suggestions for what I need please??

You dont need to use the phone with the Smart Controller,   thats really the point of it,  with the exception of a wifi hotspot.
