The new LG Nitro HD represents the company's premier Android smartphone in the United States. Without a doubt, it has a stellar spec sheet that includes 4G LTE data (AT&T), a 4.5-inch 720p HD resolution display, a dual-core 1.5GHz processor, and a 1080p HD video-capable 8 megapixel camera. It's also fairly thin, light, and attractive. The Nitro HD should fear no other device when it comes to specifications. But when it comes to real world performance, not all of its specs live up to user expectations.
