The hottest phones and tablets of Mobile World Congress 2012 (photos)

At MWC 2012, so many phones are blowing us away. Sony, LG, Nokia, Samsung, HTC, and others are keeping us all busy here at CNET. To keep track of all the great devices coming out of the expo, we've gathered them all in one slideshow that we'll keep updating as the days go by.
The ZTE Orbit is one of the first few phones to run the Windows Phone Tango OS, has a 4-inch WVGA TFT touch screen, and has a 5-megapixel camera with LED flash and autofocusing capabilities.

As one of the higher-end phones from ZTE, the Era is equipped with a 1.3 GHz quad-core CPU, a 4.3-inch display, and an 8-megapixel camera.

The Panasonic Eluga has a 4.3-inch OLED screen. For its debut in Europe and Japan, it'll run on Android Gingerbread but will be upgradable to Ice Cream Sandwich this summer.

The Panasonic Eluga Power looks more chiseled than its brother, the Eluga. It has a larger, 5-inch display, and a 1.5GHz CPU.

The Samsung Galaxy S Blaze 4G is a mouthful to say, but it's a nice device for T-Mobile. Here's what you need to know: it's got 4G HSPA+ support, of course, and also a 4-inch Super AMOLED screen, a 1.5GHz dual-core processor, and a 5-megapixel camera capable of 720p HD video. There's also a 1.3-megapixel front-facing camera.

Now available in both 7- and 10-inch models, the Samsung Galaxy Tab 2 will feature Android 4.0, a 1GHz dual-core CPU, two cameras, and 3G capabilities.

The Samsung Galaxy Mini 2--a small, simple Android smartphone--was on display at Mobile World Congress. Running Gingerbread, an 800MHz single-core CPU, and outfitted with a 3-megapixel camera, the Mini 2's specs are strictly low-end.

LG's line of L-style phones: the Optimus L7, L5, and L3 (the L7 is pictured above). While the L3 will still run on Gingerbread and has the smallest screen at 3.2 inches, the L7 and L5 will both feature ICS. At 4.3 inches, the L7 will tout the biggest touch screen of the three, while the L5 is right in the middle with a 4-inch display.

The Galaxy S Advance runs on Android 2.3 Gingerbread, has a 4-inch WVGA Super AMOLED display, a 1GHz dual-core processor, a 5-megapixel camera on the back that can record in 720p HD, and 1.3-megapixel camera in the front.

With its 3.65-inch HVGA touch screen, 5-megapixel camera, and 1 GHz processor, the Samsung Galaxy Ace Plus appears to be a decent midtier smartphone to start off any newcomer.

Samsung's Galaxy Note 10.1 runs on Android 4.0 Ice Cream Sandwich, has a 1.4GHz dual-core CPU, a 3-megapixel rear-facing camera, a 2-megapixel front-facing camera, and an S-Pen stylus.

Adding three new models to its entry-level line, Nokia unveiled the Asha 202, 203, and 302. Both the 202 and 203 will run on Symbian Series 40 and a 2G network, but only the 202 has dual SIM card capabilities. The 302 (pictured above) features Mail for Exchange and supports 3.5G data speeds.

Aimed at a younger audience, the Lumia 610 will be a cheaper Lumia model and will be one of the first few phones to run Windows Phone Tango. It'll also feature Xbox Live integration, an 800MHz Snapdragon processor, and a 5-megapixel rear-facing camera with LED flash.

Sporting a beastly 41-megapixel camera, the 808 Pureview from Nokia will also be equipped with unprecedented zooming clarity, optics from Carl Zeiss, and CD-like audio recording.

Running on ICS, the Asus Padfone has a 4.3-inch AMOLED touch screen and a dual-core processor. It also has the capability to be inserted into the Asus Padstation to become a 10.1-inch tablet.

With its 4.7-inch super LCD 2 Gorilla Glass display, the HTC One X is going for a top-tier title. It also sports an 8-megapixel camera, a 1.3-megapixel front-facing camera, Beats Audio, and a 1.5GHz quad-core Nvidia Tegra 3 processor.

Landing on T-Mobile's network, the HTC One S is equipped with Android Ice Cream Sandwich, a 4.3-inch Super AMOLED screen, a dual-core CPU, and an 8-megapixel camera that has a reported 0.7-second shot time.

Although not as robust as its two brothers, the One X and One S, the HTC One V shouldn't be written off completely. Aside from sporting a distinct chin, the device also has a 3.7-inch screen, runs on Ice Cream Sandwich, and has a 5-megapixel camera.

Huawei says the Ascend D Quad is the world's fastest smartphone. Although we're not quite sure in what terms the company means, we do know the handset has a 4.5-inch 720p HD display and the ever-anticipated quad-core CPU.

A phone that works as a projector has finally arrived with the Samsung Galaxy Beam. With a 2,000mAh battery, the device can project (at a 640x360-pixel resolution) for 3 hours straight. It's expected to be available sometime in the second quarter.

The Xperia P from Sony is equipped with a dual-core processor, an NFC chip, a lush 4-inch screen, an 8-megapixel camera, and WhiteMagic technology, which will enable it to display images and text with loads of brightness.

With its capability to smoothly display high-definition videos and games, the Sony Xperia U will showcase the same high-quality media experience as the Xperia P. The U will have a smaller 3.5-inch screen, however, and a 5-megapixel camera.

The LG Optimus 4X HD may be alphabet soup, but it's also a quad-core Ice Cream Sandwich phone with a 4.7-inch HD display. It also boasts an 8-megapixel camera, 16GB of internal memory, a 2,150mAh battery, and DLNA support.

Think the Samsung Galaxy Note is the only "phablet" option in town? Think again. The LG Optimus Vu has a whopping 5-inch display, Android Gingerbread OS, LTE network support, and a 1.5GHz dual-core processor.

Gone are the days of two-dimensional screens now that the LG Optimus 3D Max has arrived. While still stuck on Gingerbread, the device has a 1.3GHz dual-core CPU, an NFC chip, and a 4.3-inch WVGA display. Oh, and did we mention it can project images, movies, and even apps like Google Earth, in 3D without the need for goofy glasses?
