with the home button down, the cover magnets are along the left side. run a paper clip along the edge and see for your self. Those magnets, when unclose to the bottom of the RC, was causing the joy sticks not to properly calibrate for some. when the mini4 was turned 180 degrees, with home button on your right, the magnets were further away and did not effect the joy stick calibration. I, like probably most of us, started using the mini with the home button on the left, because that is where the iPhone button, cable connection is located, so just naturally set up the iPad that way, not knowing about the magnet issue until problems started showing up that didn't happen with the phone. Then someone mentioned the magnets. The tests and discussions took off from there. Not everyone has/had a problem, I for one did not, but then I never tried to calibrate the joy sticks with the iPad in place. but some did.
