The 1.3-megapixel camera takes pictures in three resolutions, from 1,280x960 down to 320x240. Editing features include brightness and white balance settings, a panorama mode, three quality settings, a self-timer, a night mode, mosaic and multishot modes, a digital zoom, 20 fun frames and three shutter sounds (plus a silent option). Photo quality was quite good--we had enough light even without a flash and colors were bright. On the downside, there is noticeable noise around the edges of our shots.
The camcorder shoots clips in one resolution (176x144) with a comparable set of editing options. Messages meant for multimedia messages are capped at 2minutes, but you can shoot for much longer in the normal mode. The SGH-A637 has a respectable 50MB of internal shared memory, but you get more space with a microSD card. A convenient meter in the camera tracks how much space is available.
You can personalize the SGH-A637 with a greeting and a variety of background colors, wallpaper, and alert tones. You can download more options and additional ringtones from AT&T using the WAP 2.0 Web browser. The handset comes with a few additional extras including Yellow pages Mobile and trial versions of MobiTV, Mobile Pix, Mobile Banking, ES Musica, Univision Movil, and WikiMobile. You also get demo versions of three games--Zuma, Tetris, and Platinum Sudoku--you'll have to buy the full versions for extended play.
We tested the dual-band, dual-mode (GSM 850/900/1800/1900; UMTS 850/1900) SGH-A637 world phone in San Francisco using AT&T service. Call quality was mostly good, though it wasn't perfect. On the upside, we enjoyed a clear signal and good voice clarity. We didn't encounter any static or interference, and callers sounded natural. But on the downside, the volume was a little soft and on a few occasions we heard a few fade-outs.
On their end, callers said we sounded fine. A few mentioned a slight background hiss, but overall the reports were positive. Automated calling systems could understand us most of the time. Speakerphone quality was decent. The phone's speaker has decent output and the audio, while somewhat harsh, was clear.
Cellular Video quality was quite good, actually. Clips took a few seconds to load, but once they were running the clarity was sharp. What's more, we didn't stop to rebuffer and the audio matched the speaker's mouth. Music quality also was satisfactory, though a headset will provide the best experience.
The Samsung SGH-A637 has a rated battery life of three hours talk time and 14.58 days standby time. Our tests reveal a talk time of 2 hours and 39 minutes. According to FCC radiation tests, the SGH-A637 has a digital SAR of 1.24 watts per kilogram.
