iPhone 6s+ and latest released iOS 9. When using Apple or Google Maps in my car, I like to put the phone in my console drink holder, upside down (speaker and lightening connector up) so I can hear the directions better. Neither Apple nor Google Maps will rotate upside down to all for this. They will rotate to either side being up, and right side up, but, will not allow use upside down. Issue or working as designed? Thanks.
