BARCELONA, Spain--If you needed any more proof that LG and Samsung had an intense rivalry, look no further than LG's new Optimus Vu. Just over a month after Samsung brought its part phone, part tablet Galaxy Note to CES, LG decided to bring a similar device to Mobile World Congress.

Like the Galaxy Note, the Optimus Vu has a 5-inch display that overshadows any other Android smartphone on the market. The 4:3 aspect ratio is ideal for e-books and browsing the Web. Even when you start on the mobile version of a Web site (like CNET), there's plenty of room to view the full version. And with LTE support, Web pages will load that much faster.

The Optimus Vu also is designed for use stylus. It's thicker than the Galaxy Note's basic stylus, which gives it a nice feel in the hand.

The Optimus Vu's main camera is 8 megapixels, and there's a second 1.3-megapixel shooter above the display. With the larger screen, the photo gallery looked quite nice.

Maps are another feature that benefit from a larger display. For some reason, though, all of the Optimus Vus on display thought they were at CES.

The main menu has a standard grid design with icons. Though the Optimus Vu only runs Gingerbread, it has a 1.5GHz dual-core processor and it supports LTE networks.

You can make a call using the alphanumeric keypad. That is, if you want to walk around with a 5-inch device next to your head.

Even with its large size, the Optmus Vu has a slim 8.5mm profile. As long as your pocket is big enough, it slips right in.
