Ok so i use an iPhone 6s with the mini and personally its all I need. Really cheap to get and dirt cheap when they have a very weak battery.. brand new battery replacement is 40$ At local screen repair store.. some people want tablet instead of phone and i was watching videos on my android tablet zte k81 ( has sim slot ) fly app isn’t compatible with it ..what do you think about mirroring the iPhone screen to the tablet lol I wouldn’t bother probably but i have a case that would allow phone to mount on tablet (Side by side ) because you will still have to use the phone for touch inputs but if its just about the screen size it would work and honestly I try to use the controller buttons to do as much as possible during flight I find it easier to hit the controller button rather than the screen. I was thinking out loud and only thought about the touch screen stuff as i got to typing at first i was thinking strap phone to back of tablet and use tablet Screen with with phone connected to controller.. essentially I just wasted mine and your time aha sorry ???? carry on
