Review: Samsung Exhibit 4G
The calling application is the stock Android app. From the dialpad, you also have access to voicemail.
In-call options include the typical features, such as adding a line, sending the call to Bluetooth or speakerphone, turning the dialpad on/off, etc. All of the features worked properly.
The Exhibit 4G also supports T-Mobile's Wi-Fi calling feature. When the Exhibit 4G's Wi-Fi radio is active, it can make calls via your home Wi-Fi network. The Exhibit 4G will not roam onto the cellular network if you step out of range from your Wi-Fi hotspot, however.

The contact app, too, is stock Android. The Exhibit 4G makes it easy to search through the contact database with but a few taps, as well as sort contacts into groups and/or favorites.
The Exhibit 4G also includes the Samsung "Buddies Now" home screen widget that can be populated with links to up to nine buddies. It loads up a full-screen carousel with the faces of your nine top friends. Scroll through the list for easy access to calling and messaging tasks via the action bubbles that appear in the widget next to your friends' avatars.
If you want to look at a buddy's entire contact card, simply press their avatar and you'll be taken into the contact application. This app can be used instead of setting a handful of contact shortcuts to the home screen.
