The 1.3-megapixel camera takes photos in five resolutions--from 1,280x960 down to standard VGA. Other camera features include a flash, a self-timer, color effects, white balance, a multishot mode, three quality settings, ISO, spot metering, and a choice of shutter sounds. The camcorder shoots clips with sound in two resolutions (320x240 and 176x144) and offers a choice of editing options similar to the still camera. Clips meant for multimedia messages are capped at 15 seconds; otherwise you should be able to shoot up to an hour of video. The SCH-U620 comes with a respectable 69MB of internal memory, but you're better off investing in a healthy microSD card. Photo and video quality was decent, although we found the colors to be a bit washed out.
The phone book holds as many as 500 entries, with multiple contact information per entry. With Bluetooth support, you can wirelessly connect a PC or other Bluetooth-enabled devices (including stereo headsets) to the phone. We had no problem exchanging contacts between the SCH-U620 and a Samsung SPH-A640. Other features include a vibrate mode, text and multimedia, voice commands and dialing, messaging, a calculator, a calendar, an alarm clock, a world clock , a stop watch, and a notepad. There's also mobile instant messaging, which supports AOL, MSN, and Yahoo services.
We tested the SCH-U620 in the Chicago and San Francisco areas, though the latter currently is not a V Cast Mobile TV market. Call quality was generally good. On our end, voices sounded loud and clear. Similarly, callers had no problems hearing us, even when we were using the phone outdoors, although they could tell we were using a cell phone. Reception remained strong in most areas, and the EV-DO connection was reliable. Downloading a four-minute music video took about two minutes over Verizon's EV-DO network, which isn't bad.
The Mobile TV picture quality is stunning, provided you're able to get a strong signal. Forget the jerky, heavily pixilated video images you've become accustomed to seeing streamed over 3G networks; Mobile TV delivers crystal-clear, full-motion images at 30 frames per second (EV-DO streaming services cap out at 15fps). The display, however, is small for video use, especially when you're staring at it for more than a half hour. We're looking forward to the bigger display on the LG VX9400.
Rather than relying on streaming over a 3G network, Mobile TV uses a portion of the UHF spectrum different from the one used for standard over-the-air broadcasts. As such, the cellular and TV signals are independent from one another, and you don't need any calling bars to watch the TV programming. We saw no lag between audio and video, and the video itself was crisp and vibrant. Some programs displayed a bit more artifacts than others, but nothing like previous mobile video-streaming services. Channel hopping on Mobile TV isn't quite instantaneous, but it's quick enough--there's about a two-second lag between selecting a channel and the feed coming through, about what you get with satellite TV.
Unless you're in a fairly quiet room, you'll want to use a headset to listen to your broadcasts. The speaker isn't quite loud enough to hear clearly in public environments, and the quality is somewhat tinny. Even while riding in the passenger seat of a car with the windows up, we often had to strain to hear everything. Also, we often had trouble getting a TV signal indoors unless standing near a window. Even then, the signal was intermittent, causing frequent hiccups in the broadcast.
The Samsung SCH-U620 has a rated battery life of 3.5 hours of talk time and 10 days standby time. Our tests showed a talk time of 2 hours and 50 minutes instead. According to FCC radiation tests, the SCH-U620 has a digital SAR rating of 0.958 watts per kilogram.
