Sync contacts from iPhone to Gmail I cannot sync contacts from my iPhone to my Gmail account. I have a standard Google account setup in my Mail, Contacts, Calendars settings (Exchange is not available to me). Also, my Gmail is set as my default account. 

Note, my contacts are synced from Gmail to my iPhone, but not in reverse; meaning, any contact I add on my phone never makes in into my Gmail contacts. I'd like to not have to do this manually or through iTunes.
Check your default contacts account on your iPhone by tapping through Settings > Mail, Contacts, Calendars. Next, under the CONTACTS section, tap on "Default Account". Finally, tap your Gmail account from the list. 

Now every new contact you create on the iPhone will automatically push to your Gmail account.
