There’s an even faster way to call someone than going to your Favorites—put her on speed dial. When you’re in the Phone app, at the Dialer, Recent, Contacts, or Favorites screens, tap the Menu key, and then tap “Speed dial setup”. From the screen that appears, tap “Add Speed dial”. Choose the person you want to put on speed dial, and they’re added to the list, with a number assigned (1 for the first person you add to speed dial, 2 for the second, and so on, up to a total of 9). Eventually, you’ll find yourself remembering the speed dial numbers for close friends and family members.
Using speed dial is exceptionally easy. On the Dialer, press and hold the key that corresponds to the number the person is on your speed dial list. The Droid X makes the call.
