LG hasn’t launched a high-end Android smartphone in the U.S. for some time now — sure, it shipped the Optimus on multiple carriers, and Verizon launched the Ally a few years back, but neither was capable of holding a candle to other first-rate devices. That all changes with the G2x however, which is no doubt LG’s answer to Samsung’s Galaxy S family of smartphones in the United States. Its spec sheet is enough to leave other phones shaking in their boots. Dual-core processor, 4G radio, 1080p video — it has all the trappings of a top-of-the-line handset. I have been using, abusing, and confusing the G2x for the past few days and am ready to levy judgement on LG’s first serious smartphone contender. Want to know if the T-Mobile G2x has what it takes to be your next high-end smartphone? Hit the jump to find out.
