This is the one thing that seemed off. I don't have any preference for one ear over the other. If I hold the phone up to an ear, it would depend on what I wanted to do with the other hand. If I'm writing, I would hold the phone in my left hand to my left ear. If I'm typing one-handed, I would type with my left hand while i hold the phone in my right hand to my right ear.

If I went to listen up against a door, it would depend on other things which ear I used, like which ear might already be closer to the door.
