The touch screen also supports handwriting recognition. It was a little easier than using the keyboard, but the recognition wasn't always accurate. And without a stylus, it feels a little weird to use your finger. The D8 is not a phone for the prolific messenger.
The remaining exterior controls include a volume rocker on the left spine, and a camera lens and stereo speakers on the D8's rear face. An extendable antenna for the FM radio, a proprietary connection for the included charger, USB cable, and a headset are located on the phone's bottom end. Keep in mind that you'll be able to use only one peripheral at a time. The SIM cards slots and the microSD card slot are located behind the battery; we'd prefer that the latter be more easily accessible. On the upside, the D8 comes with a 256MB microSD card and an extra battery.
The Duet D888 has a 500-contact phone book with room in each entry for three phone numbers, an e-mail address, a company name, and a birthday. Each SIM card stores an additional 250 names, and dedicated customer service and emergency numbers. You can organize callers into groups and you can pair them with a photo or video and one of 15 polyphonic ringtones. Alternatively, you can use your own music files as ringtones and compose your own melodies. For entering text, the D888 supports English, Spanish, Vietnamese, and Chinese.
Essential features include a vibrate mode, a file manager, text and multimedia messaging, a calendar, a to-do list, an alarm clock, a world clock, a calculator, a stopwatch, and a currency converter. You'll also find Bluetooth, a voice recorder, chat, an e-book reader, call timers and recording, and a speakerphone.
The Duet D8's multimedia features are similar to the D888's. You'll find a 2-megapixel camera with video recording, an FM radio, a video player, and a music player. As on the D888, most offerings, particularly the music player, are very basic--you won't find many editing and user options. Yet FM radio recording and a rudimentary form of mobile television are available. The quality, though, was equally as horrible as on the D888. Photo quality from the camera was forgettable as well. Our images were washed out and blurry.
You can personalize the Duet D8 with a variety of wallpaper, screensavers, greetings, and functions settings. The handset has a WAP Web browser, but you'll need the necessary multimedia settings from your carrier if you want to use it. Gamers get just one title called Magic Sushi.
We tested the quad-band (GSM: 850/900/1800/1900) in San Francisco using T-Mobile and AT&T service. Call quality was satisfactory on both networks with little difference between them save for a bit more GSM buzz on AT&T. On all calls voices sounded natural, though the volume was rather soft. When speaking in noisy environments we had trouble hearing if the other person was on a call phone.
On their end, callers were relatively pleased. They could tell were using a cell phone, but most didn't report significant problems outside of some background noise. Speakerphone calls offered decent quality on our side, but some callers had trouble hearing us. And as on regular voice calls, the volume was too soft.
