Below the display is a traditional navigation array consisting of a four-way toggle with a central OK button, two soft keys, the Talk and End/Power controls and a Back button. There's also a dedicated speakerphone button (nice) and a unique Text key that serves as a shortcut to the messaging menu. And speaking of shortcuts, the toggle can be set to give one-touch access to four user-defined functions.
The keypad buttons are raised ever so slightly above the surface of the phone, which makes for tactile dialing. We also liked that the central column of keys has a slightly darker color. All the buttons are backlit for easy dialing by feel.
The LX150 includes all the essential features you've come to expect from a cell phone. The phone book holds 500 contacts with room in each entry for five phone numbers, an e-mail address, a Web address, and notes. Callers can be organized into groups, and you can assign them one of 24 (32-chord) polyphonic ringtones as well. You also can pair them with a photo, but you'll need to get photos on the phone your own way since there's no camera. Other basics include a vibrate mode, text and multimedia messaging, voice dialing, instant messaging and POP3 e-mail, a scheduler, an alarm clock, a voice memo, a notepad, a calculator, a world clock, and the handy LG tip calculator. The LX150 also supports Bluetooth and a full duplex speakerphone, both of which are nice to see on such a low-end model.
You can personalize the LX150 with a variety of alert tones, screensavers, and color skins. If you're bored with the integrated options, you always can download more choices with the WAP 2.0 wireless Web browser. Other applications are slim; you get demo versions of four games (Midnight Pool, Pac-Man, Tetris, and Zuma) and trial versions of MobiTV and Sprint Radio.
We tested the dual-band, dual-mode (CDMA 800/1900; AMPS 800) LG LX150 in San Francisco using Sprint's service. Call quality was decent with clear conversations marred only occasionally by some slight scratchiness. Volume was loud enough, and though callers could tell we were using a cell phone, they reported no significant problems. With the speakerphone, calls were tinny, so we didn't want to use it too often. On the other hand, Bluetooth calls were satisfactory. The LG LX150 has a tested talk time of 3 hours and 53 minutes. According to FCC radiation tests, the LX150 has a digital 0.76 SAR rating of watts per kilogram and an analog SAR rating of 0.96 watts per kilogram.
