The music player interface is like others we've seen; you get the usual player controls plus options for repeat, shuffle, and creating and editing your own playlists. It also has up to six preset equalizer settings and a visualizer. You can send the player to the background if you want to multitask in other parts of the phone.
The 2-megapixel camera on the Prime has a healthy array of settings. You get five resolutions, three quality modes, three color effects, five white-balance presets (including an auto setting), a self-timer of up to 10 seconds, automatic or manual ISO, 2x zoom, three shutter sounds plus a silent option, night mode, sequential shot mode, brightness, and the capability to build a cross-section or tri-section of images. Its photo quality was bland, and its colors looked dull and slightly gray. Images weren't as sharp as we would like. The Prime has video mode as well--you can record in either 320x240- or 176x144-pixel (QVGA or QCIF) resolutions.
You can customize the Prime with wallpaper and screensavers, and you can download a few games and apps from the AT&T AppCenter. The phone comes with Brain Exercise, Bubble Bash 2, I-play Bowling, Tetris, World Series of Poker, Mobile Banking, My-Cast Weather, and Pocket Auction.
We tested the LG Prime in San Francisco using AT&T's service. Call quality was quite pleasant on the whole. On our end, we heard our callers very clearly with good volume, though they sounded rather robotic and fuzzy at times.
On their end, callers, too, said that we sounded very machinelike. However, they could still hear us and we carried on a conversation without problems. There was the occasional hiss and skip of static, but it was not distracting. Calls made with its speakerphone did not fare so well, though. Callers had to ask us to speak up most of the time as we sounded too soft and far away. We thought they sounded loud and clear
As for audio playback, we thought the music sounded very loud and brash with not a lot of nuance or bass, especially via the phone's speakers. We encourage you to use a headset, especially since the phone has a 3.5mm headset jack.
As the phone doesn't support 3G networks, we didn't expect too much out of the phone's EDGE speeds. The Prime managed to load the mobile version of the BBC Web site in about 19 seconds. Still, it was on par with what we expect from a prepaid phone.
The LG Prime has a rated battery life of 4 hours talk time and 16 days standby time. We ran the Prime through our battery drain tests and had a result of 3 hours and 45 minutes. According to FCC radiation tests, the Prime has a digital SAR of 1.1 watts per kilogram.
