Review: Samsung Gravity Smart
The Gravity Smart's screen is better than the Samsung Dart's but not by much. It manages to stretch 0.1 inches further across the diagonal at 3.2-inches, and packs in 320 x 480 pixels. The size and pixel density make it an average display. Some graphics and icons look good, others don't, and text can be jagged from time to time. As far as brightness goes, it was adequately bright for indoor use, but was near to unusable outdoors.Signal
The Gravity Smart did a very good job connecting to T-Mobile's voice and data network. At my home, it displayed an above-average four bars of signal strength. In my travels around northern New Jersey, it always remained actively connected to the network. During my tests, the Gravity Smart did not drop any calls, did not miss any calls, nor did it have any trouble connecting dialed calls. Each and every one went through on the first attempt. Data sessions were also good. I had no trouble connecting to T-Mobile's data network, and never saw the Gravity Smart drop down to EDGE.Sound
The Gravity Smart left a bit to be desired in the sound department. First off, calls came through muffled, as though the person with whom I was conversing was talking through a styrofoam cup. I didn't notice any clipping or static, but the speaking-through-a-sock effect was disappointing to say the least. Second, the earpiece speaker isn't nearly loud enough. Set to full volume, I was unable to hear conversations over the construction taking place outside on my street. The speakerphone was much louder than the earpiece, but had the same muffled characteristics. Ringers and alert tones, on the other hand, are perfectly loud. Set to max volume, they were quite boom-y. The vibrate alert is also plenty loud.

I found the Gravity Smart to have very good battery life. It powered its way through two days at a time quite consistently and even had a bit of juice left over for the morning of the third day. Charging every other night will be sufficient for most users, though heavy use of all the radios - Wi-Fi for browsing, GPS for navigation, etc. - does take a toll.
