Remove Gmail contacts from iPhone contacts list My iPhone has pulled in all contacts from my Gmail account into my contact list. It’s gotten so out of hand that it’s difficult to find contacts I need. 

Is there any easy way to remove these and keep them from coming in again?

iPhone 6, iOS 10.3.3
Go to Settings → Contacts → Accounts → your Gmail account and turn off Contacts.
Choose ‘Delete from iPhone’ to remove them from your iPhone contacts list.
