As only the second United States wireless service provider to offer a high-speed 4G LTE mobile internet network, AT&T has just three phones capable of handling that system's high performance levels. The most recent of these, LG's Nitro HD, falls short in some areas when compared to other AT&T 4G phones, while still standing out in a general sense, according to PC Magazine.

The news source reports that the Nitro HD runs on Android 2.3.5 Gingerbread, and may receive an upgrade to 4.0 Ice Cream Sandwich in the future. Its 1.5 GHz dual-core processor is one of the best currently available on the smartphone and smartphone accessories market, particularly with regard to supporting media ranging from high-resolution games and video content to high-quality music files.

The device's media performance is bolstered by its 720p HD screen, a feature only available on one other smartphone on the U.S. market – the HTC Rezound. On the Nitro, this provides a bright display with rich visuals at a high rate of pixel density.

According to TechCrunch, the Nitro HD is not without drawbacks – its hardware features several deficiencies in quality, and its software performance suffers when compared to similarly equipped phones.
