How to Merge Your Google Contacts Database with Glass
Synchronizing your Google Contacts database with Glass can take a while if your database has multiple contacts for several people. Fortunately, Google Contacts makes it easy to clean up your database by merging information in all contacts that have the same name. To merge contacts, follow these steps:
Open the Google Contacts webpage.
Log in to Google Contacts, if necessary, using your Google e-mail address and password.
In the contact list, tap or click the More button and then tap or click Find & Merge Duplicates on the resulting menu.
You see a list of contacts that contain duplicate data, such as the same e-mail address.
Merge the contacts by tapping or clicking Merge Contacts at the top of the list.
You can view information about merging two or more contacts manually at Google Support.
