This is the reason you have a contacts app: If you are actively engaged in a phone call and you want to ADD or MODIFY a new/current contact, you can NOT do this by hitting the contact button thru the phone app. You can ONLY add or edit a contact, when engaged during a phone call, by hitting the contact APP. It would roll like this: You: *ring* *ring* Me: hello? You: hey, what up? Me: nada, you? You: you hear Angela got a new phone number and email address after she broke up with you? Me: NO! What is it!?!? You: I’m not tellin’…….she broke up with you…..you’ll just stalk her. Me: no I wont……tell me! You: ok, just don’t tell her I told you…….555-555-5555 and ‘email@example.com’ Me: thanks See, now I couldn’t have updated her info through the Phone/contact……..I had to use the Contacts App for this.
