Google is getting ready to push out the latest update for Google Glass—numbered XE 20.1—and with it is coming some pretty major changes to how contacts are handled, notably allowing users to access all contacts by voice via Google Contacts. Also included in this update is the ability to actually choose which method you would like to use when sending a contact a message—Hangouts, email, or SMS.
Your entire phone address book is now available on Glass thanks to Google Contacts. You can access 20 of your most recent and starred contacts by voice and the rest are just a swipe away. Starring a contact is really easy. Just find them in your phone and click the star. If the star is filled in, then the contact has been favorited.
