LG took the wraps off a number of smartphones leading up to Mobile World Congress this past week, and now we’re finally getting some hands-on time with all of them. The LG Vu garnered most of the attention last week thanks to its Galaxy Note-like supersized stature, but the high-definition LG Optimus 4X HD definitely shouldn’t be ignored. This quad-core Tegra 3-powered Ice Cream Sandwich phone features a 4.7-inch 1280 x 720-pixel IPS display that is definitely more impressive than earlier LG screens, but it can’t quite compete with the Super AMOLED panels Samsung has been using on its recent smartphones. LG also included a new version of its Optimus UI on top of Android 4.0 and among the variety of Android skins on the market today, LG’s is definitely one of our least favorite. Navigating the UI and multitasking is lightning fast thanks to the Tegra 3 chip though, and this is easily among the most impressive smartphones LG has built to date.
