I am new to the forum and not a technical guy. When my friend set up my DNA he brought over every contact from social media and other mail sites etc. I would like to delete these contacts so when I want to send a text I don't have to search through so many names. When I click on the people icon in the phone , I have the only contacts I want. However if I want to send a text and click on "compose" and click "people", my contacts I want come up, and then, below that are listed all the social media and other email contacts and more. Those are the ones I need to delete. Please advise and thank You!!
