When I go into the phone screen (for making calls), there is a single contact highlighted on top. This was the case on the Galaxy Nexus, as well as the Nexus 5 I just got to replace it. Does anyone know how to remove and/or change who that single contact is? For me, Google somehow decided it is my wife, but on my wife's phone, Google decided to put a (male) colleague of hers. Jokes aside, she'd like to change it, and I haven't been able to figure out how. Any help would be appreciated.
