Aren't you not supposed to have your phone or tech near magnets, or has technology moved passed that? Also to anyone who has this mount, it looks like you need to place part of the magnet on the inside of a case to connect, but I don't use a case. Do I have to place that on the back of my phone and keep it there or put it on anytime I want to mount my phone in the car?
