How do I remove google contacts? I have 3 google accounts which have a bunch of auto-populated email addresses and contacts I have never intended to add to my android

I went to Settings > Accounts > Google > foobar@gmail.com > Contacts > Switched toOFF

HOWEVER when I go back to the phone app, all of the garbage auto-populated email addresses are STILL THERE. And when I select one of them, it clearly indicates with a google logo it was "synced from google account". 

I intentionally don't use Google stuff. I want it off my phone.

You have done half the work.

By this query we can understand that this new Google's people details sync should be turned off too together with Google contacts as this new service connecting you with others via some other platforms such as Google+.

Follow these steps:

Go to Contacts app-Open contact's settings(by touching 3 dots on the upper right corner)-Contacts to display(select account from which you want contacts from such as from 'phone contacts' or from a specific 'Google account'.

It's done.

Attaching picture to see inside settings of contacts app.



Note: Be specific with an account as you can see in the picture samsung is taking contacts from all the apps that are telegram,paytm,hike, and even from samsung pay.
