Review: Huawei Activa 4G for MetroPCS
The Activa uses the stock Android 2.3 calling and contacts applications. One thing I like is that there's a little shortcut to the SMS app from the phone dialer. This means you can type in a new number and then easily start an SMS with that person instead of dialing the number.
The Activa offers haptic feedback when you dial numbers on the touch display. Call features include mute, speakerphone, add a line, etc.
The Activa will import all of your Google or Exchange contacts if you have them. Adding Facebook and Twitter friends is optional. Contacts can hold innumerable phone numbers, email addresses, notes, and so on. The Activa doesn't have any nifty contact widgets for the home screen; only the stock tools are available.
