Review: Samsung DoubleTime for AT&T
The DoubleTime uses the stock Google calling and contacts applications. From the home screen, press the phone icon and the dialer pops open. The DoubleTime offers haptic feedback when you dial numbers on the touch display.
The DoubleTime will import all of your Google and Exchange contacts if you have them. Adding Facebook friends is optional. If you press the area next to the profile picture/Android, it will open the contact's page.
