The 1.3-megapixel camera takes in pictures in seven resolutions. Editing options include a night mode, brightness and white balance settings, six color effects, exposure metering, a 4x zoom, three shutter sounds (there's no silent option), multishot and mosaic shot modes, a self-timer, and 28 fun frames. While that's an impressive array of options, photo quality was mediocre. Colors weren't bad, but our images were too bright and had too much noise. There is an image editor, but it doesn't help much. There are three resolutions to select from when using the camcorder, which also records sound. Editing options are similar still to the camera, but here again you don't get the benefit of a flash or light. Clips meant for multimedia messages are capped at just over a minute; otherwise, you can shoot for as long as the available memory permits.
When finished with your photos, you can upload them to an online album or journal or you save them to the phone's memory. The T339 comes with about 20MB of internal storage, but you can use a microSD card for more space. Also, you can take audio postcards, a photo with a sound file attached, that you can send to friends. The postcard comes in a special frame with a postmark graphic.
The T339's generic music player barely makes an effort, but it is fine for very short stints. The interface is minimalist with just simple visualizations, but it's easy to understand. Features are limited to shuffle and repeat modes, but you can use MP3 files as ringtones. Getting music on the phone was easy whether you're using a USB cable, a memory card, or wireless transfer. Music quality was unimpressive, but fitting for a music player like this.
You can personalize the T339 with wallpaper, themes, background colors, and alert tones. If you want more options or more ringtones you can download them from T-Mobile's t-zones service using the WAP 2.0 Web browser. The T339 comes with three Java demo games--Brain Challenge, Platinum Sudoku, and Forgotten Warrior--you'll have to buy the full version for extended play.
We tested the tri-band (GSM 850/1800/1900; EDGE) Samsung SGH-T339 in San Francisco using T-Mobile service. Call quality was decent, but it wasn't quite as good as on the Nokia 6301. Voices were clear the majority of the time, though some of our friends sounded a bit fuzzy. Also, the volume could be a bit higher. The signal was consistently strong, however.
On their end, callers said we sounded fine. They could tell were using a cell phone, and some of our friends reported that the phone picked up some background nose, but by and large we didn't hear major complaints. Automated calling systems could understand us except for when we were speaking in a noisy place. Speakerphone calls were decent, though the volume could be louder here as well.
Wi-Fi calls provide better audio quality. As is the case with most Wi-Fi calling services, there was a very short conversation lag, but we were quite pleased with the experience. Callers reported no issues on their end.
The T339 has a rated battery life of 6.4 hours talk time and up to 11 days standby time. Our tests revealed a talk time of 7 hours and 50 minutes. The T339 has a digital SAR rating of 0.733 watt per kilogram.
