The VGA camera takes photos in four resolutions (from 640x480 down to 120x96). Other editing options are standard. You'll find a self-timer, and adjustable white balance, four color effects, brightness settings, exposure metering, and a digital zoom. You also can choose between different sounds for the zoom, brightness, and shutter. The SGH-T139 does not record video. Its photo quality is good for a VGA shooter. There's a bit of image noise, but colors looked natural.
You can personalize the T139 with wallpaper, background colors, greetings, and alert tones. More options are available from T-Mobile's T-Zones service. The handset includes demos of four games: Tetris, 5th Grader, Midnight Pool 2, and Family Guy Uncensored. You'll need to buy the full versions for extended play. The SGH-T139 has about 6MB of memory, so you'll need to monitor space carefully.
We tested the dual-band (CDMA 800/1,900MHz) phone in San Francisco using T-Mobile service. Its call quality was satisfactory overall. There was a slight metallic tinge to the audio, but the signal was clear, and we could understand our conversations. We also appreciated that the loud audio enabled us to hear in most environments.
On their end callers said we sounded fine. They could tell that we were using a cell phone, but complaints were limited to the metallic sound that we heard.
The SGH-T139 has a rated battery life of 4 hours talk time and 6 days standby time. It has a talk time of 4 hours and 3 minutes in our tests. According to the FCC, the T139 has a digital SAR of 0.59 watt per kilogram.
