Answers to some of your questions about synchronizing contacts between your Samsung Galaxy S III and Gmail
How does my Samsung Galaxy S® III back up and restore contacts with Gmail™?
If you sign into a Google™ account during the initial setup process, your Samsung Galaxy S III automatically synchronizes contacts with your Gmail account.
If you add contacts to your Samsung Galaxy S III before signing into your Google account, your contacts don't synchronize with Gmail. They save as Phone Only contacts.
After you've associated your Google account with your Samsung Galaxy S III, anytime you add, import, or transfer a contact, your device prompts you to choose where to save the contact. Contacts don't synchronize with your Google account unless you select Google Account.
