Google Contacts in Phone App
So I have just got my new HTC One today and something is annoying me in the phone app. I have synced my phone with my Google account and all of my Google based data appeared on the phone, that's fine. I noticed that under the "Sources" menu in the top left of the phone book in the phone app that I have a "Phone" source which is the one I'm using and all my numbers are in and I have another one called "Google". I have unticked this filter as I don't want them showing in my PhoneBook but now I'd like to remove the source itself. Does anyone know how this would be done?
