The Android 4.4.3 update included lots of bug fixes but very few new features. One of the new features included is a redesign of the Google Phone app. The phone app still functions the same. What is new here is the theming of the app. Your favorite contacts list continues to be the main screen of the dialer, favorites include larger cards, there is an overflow button that will open the full contacts list. You can rearrange your favorites by long pressing the individual card and moving it around to the appropriate place. The dialer screen is updated and looks much cleaner with a white and blue theme. This is a full screen dial pad. You can dial a number or spell out a name with the dialer just as before. Icons have all been updated, along with the rest of the theme.
