The new Google Contacts (Material) seems to have made a clear cut between
"My Contacts" (the contacts which were before in the "My Contacts" group) and which are synchronized to mobile devices
and "other contacts" which is a trashbin-looking group with contacts auto-generated, or the ones which were not in the old "My Contacts" group.
What is the status of "other contacts"? Is it possible to have it synchronized? is it possible not to have it auto-populate?
