Since the Gravity 2 is a messaging-focused phone, it was only fitting that it comes with several messaging options. Not only can you send the normal text and multimedia messages, you can also send instant messages (from AIM, Yahoo, and Windows Live), audio postcards (which are framed photos with an audio attachment), and e-mail. You can create e-mail accounts from a variety of providers, like AOL, Yahoo, Comcast, and more, but bear in mind that you can't just enter in a POP3 or IMAP server address, so your provider may not be supported.
The Gravity 2 comes with a rather basic music player. The tracks are organized by artists and albums, and you can also create and edit your own playlists. You can tweak the visualizations during music playback, add up to nine sound effects, which include "Wide" and "Surround" sound, and set it so that the music plays in the background when you're in other parts of the phone. Of course you can also set the tracks on repeat or shuffle. You can load your music via a microSD card. The Gravity 2 supports MP3, AAC, and AAC+ file formats.
We were also pleased to see that the Gravity 2 comes with a slightly better camera; a 2.0-megapixel instead of the 1.3-megapixel on its predecessor. It can take pictures in four resolutions (1,600x1,200, 1,280x960, 640x480, and 320x240), three quality settings, five white balance presets, and five color effects. Other camera settings include a night mode, a self-timer, three shutter tones plus a silent mode, three metering modes (Matrix, Center-weighted, and Spot), and five shot modes (Single, Continuous, Panorama, Smile shot, and Mosaic). Panorama mode stitches photos automatically as you pan from left to right, and Smile shot automatically takes a photo as soon as the camera detects a smile.
Photo quality was decent. Images looked sharp without a lot of blur, though the colors did seem a bit muted and overcast. There's also a built-in camcorder on the Gravity 2. You can record clips in just 176x144 resolution, in either normal length or limited for MMS. You can also choose to record with or without audio. Other camcorder settings are similar to those of the still camera.
You can personalize the Samsung Gravity 2 by adding wallpaper, screensavers, and alert tones. It also comes with a few games, like demo versions of The Sims 3 and Tetris. You'll have to purchase the full versions of the games to play further. To buy them as well as additional graphics and sound files, you can go to the T-Mobile store via the Web browser.
We tested the quad-band (GSM 850/900/1,800/1,900; UMTS/HSDPA) Samsung Gravity 2 in San Francisco using T-Mobile's network. We were quite pleased with the call quality overall. On our end, we could hear our callers very clearly with hardly any static or noise. Their voices sounded quite natural as well.
On their end, callers were quite impressed with the call quality. They said our voice sounded clear and natural, though they would've liked a bit more volume at times. In speakerphone mode, we thought our callers sounded slightly tinny, but with plenty of volume. Callers could hear us loud and clear as well, but with a heavy echo effect and a low hum in the background.
We were also impressed with the 3G speeds. We managed to load a full HTML page like the CNET front page in around 15 seconds, for example. We also had no trouble getting a 3G signal in our neighborhood in downtown San Francisco. We also managed to stream video with hardly any buffering time at all. Still, streaming video quality seemed pixelated and choppy.
The audio quality from the speakers was all right, but nothing spectacular. The bass was a bit too light, and the music overall sounded harsh. We would recommend using a headset for better audio quality.
The Samsung Gravity 2 has a rated battery life of 5.5 hours talk time and 12.5 days standby time. It has a tested talk time of 5 hours and 55 minutes. According to FCC tests, the Gravity 2 has a SAR of 0.547 watts per kilogram.
