Why when I disable contact app on Samsung Galaxy Note 2 phone dialer disappers

[AC Question]

I disabled my contacts app and the phone Icon also disappeared...I enabled contact app and icon came back. Why are the two connected. I scrolled through permissions and at the very bottom is a phone icon with Read_Call_Settings is that normal

Welcome to the forums. It doesn't really surprise me that Contacts and Phone are linked, as the two are rather symbiotic. I did check my Note 5, and I have the same permission. I'm guessing that it's there so that the Phone app can communicate with the Contacts to give you caller ID from that contact.
