From my Nexus 5 I mistakenly synced my contacts from one of my gmail accounts. Suddenly, all of those contacts appeared in my phone's "contacts' list, and they also all appeared in my "phone" app's contact list. Yikes! I was able to fix the problem in my main contacts list by just choosing to display contacts from my primary gmail account and not the other two accounts I maintain. However, I have not been able to figure out how to remove all the unwanted contacts from the phone app's contacts list, other than deleting them one by one - all 200+ of them. Any ideas out there? Thanks.
