Every phone I've ever had allowed me to add a number from call history to an existing contact. When I go to call history, press a number, the option I get requires me to add a new contact. Earlier today, I stumbled onto the mechanism to add a missed call phone number to an existing contact, and I want to find it again. I read a similar post which says to use the people and type in the new number. In order to do that, I have to write down the number from call history, go to people, and type in the number. A big pain. Please help.
