A button that says Maps will appear on this portion of the Contacts card. Tap on it and you’ll be able to see the person’s location in Google Maps. Besides making sure that your Contacts card for a specific friend or family member includes his/her Gmail address, and that the person shares his/her Google Maps location with you, you must use the Google Contacts app on your Android phone and not one offered by the manufacturer of your phone.
