Why isn't contact name showing?

[Android Central Question]

On my galaxy j7 the contact name is not showing when I receive a call from that contact. Just the phone #, but it does show in the call history.

Because AT&T screwed something up. See this thread on this issue - https://forums.androidcentral.com/a...8-active-quit-showing-my-contact-names-2.html
