The C168i's navigation controls are a mixed bag. The toggle and central OK button are raised above the surface, which gives them a tactile feel. They are slightly cramped, however, so you may want to give the controls a test run first. The toggle can be set as a shortcut to four user-defined functions. On the downside, the soft keys are flush with the surface of the phone and appear to blend in with the black border surrounding the display. We'd like more tactile definition.
Fortunately, the backlit keypad buttons and the Talk and End/power keys are raised, which made it easy to dial by feel. The numbers on the keys are small, but that's understandable on such a compact phone. Yet we're really disappointed that the C168i doesn't have an external volume rocker. That means you must remove the phone from your face during a call to adjust the volume. The only features on the exterior of the phone are a charger port on the left spine and a headset jack on the phone's top end.
The Motorola C168i has a small phone book with room for 600 contacts. Each entry holds five phone numbers as well as a single field for a note, an e-mail address, a postal address, or a Web address. You can save callers to groups, but you can't assign any of the 27 polyphonic ringtones to specific callers. Features on the C168i are strictly functional. You're limited to a calculator, a calendar, an alarm lock, text and multimedia messaging, and a vibrate mode. There's no speakerphone, unfortunately.
You can personalize the C168i with a variety of wallpaper, color styles, and alert sounds. You can download more options and ringtones with the WAP 2.0 wireless Web browser. You get three Java (J2ME) games--Soccer, Rebels, and Crazy, but gameplay on such a phone isn't very fun.
