We've been at Mobile World Congress in Barcelona, Spain all week, reporting live from the show floor on the newest in smartphone and tablet technology.

We've visited the stands of Sony, HTC, LG, Samsung, ZTE, Asus, Huawei and more to get a first-hand look their latest products:

Hands-on with the Sony Xperia Z tablet

Sony says its Xperia Z tablet is both water- and dust-proof. We had to see the 10-inch Android slate for ourselves. 

Hands-on with the YotaPhone

Why have one screen when you can have two? The YotaPhone explores this concept with an LCD screen on one side of the smartphone and an E-ink screen on the other. We just had to see the dual-screen YotaPhone in person

Hands-on with the HTC One

We couldn't wait to see HTC's so-called "ultrapixel" technology in effect at MWC. Marketing speak for "megapixels from large photosites," the camera is nonetheless interesting with a 4MP sensor using pixels are similar in size to those found in enthusiast compact cameras. Read our complete hands-on review of the HTC One

Hands-on with the Huawei Ascend P2  

Chinese manufacturer Huawei calls its Ascend P2 the "world's fastest smartphone." This bold statement is based on the device's 1.5 GHz quad-core processor and Cat 4 LTE connectivity which should enable download speeds of up to 150 Mbps. The phone's camera features a 13MP back-illuminated sensor and there's a physical shutter button on the phone's right side. See how we found the Ascend P2 in hand.

LG Optimus G Pro

LG debuted the Optimus G Pro at MWC, a 5.5-inch 'phablet' with a 13MP back-illuminated CMOS sensor. Read how we found the device

ZTE  Grand Memo

With its 5.7-inch display the Grand Memo from ZTE firmly falls into the "phablet" category where it competes with devices such as the Samsung Galaxy Note or LG Optimus Vu. We gave the ZTE smartphone a play at MWC.

Samsung Galaxy Note 8.0 tablet

At eight inches the Samsung's Note 8.0's screen is marginally larger than the iPad Mini's, which the new device is squarely aimed at in the small-tablet segment. The Note 8.0 features a 5MP rear camera which allows for 1080p video recording and a 1.3 MP camera on the front for video calling and (we suppose) self-portraits. We gave it a try at MWC.

Asus Padfone Infinity

Taiwanese company Asus has launched the latest model in its Padfone line, the Padfone Infinity, a smartphone and a "dumb" screen with a dock that the phone can slide into, turning the combination into a fully-fledged tablet. We decided to see if the device really is more than meets the eye.
