To open a list of your favorite contacts

Open the Contacts app and tap the Favorites tab (at the top of the screen).

Favorites lists the contacts you’ve designated as your favorites (at the top of the screen) and entries you’ve contacted frequently (at the bottom of the screen). While viewing the Favorites tab, tap the Menu icon (at the upper-right corner of the screen) then tap Grid view (or List view) to change how your favorites are displayed.
