3.Call, Text, or Navigate to Your Contacts' Address by Tapping Their Photo

This feature is so old that many Android users may never have known it was hiding there all along. In many apps within Android—including the dialer, contacts, Gmail, Messaging and more, you'll see a small arrow in the corner of the contact's picture. This means you can tap their photo and quickly jump to all the different ways you can contact them. If you have address info stored, you can even easily open up Google Navigation to their house. This is one of those features that rewards those that keep their contacts in order, so if yours are a mess, it may be beneficial to do some spring cleaning and join all those duplicate entries.
