Today I discovered that if you have a Samsung note 4 or iPhone 6, the phone rests perfectly on the two knobs for the unit. Sure it might not be ideal for some people but since the phone covers the screen for the unit and then some, it's almost like you have a brand new head unit. During my commute home, the phone didn't fall off the knobs. I have a note 4 but I would assume it would work for the iPhone 6.
