BARCELONA, MOBILE WORLD CONGRESS — European carrier Orange is at Mobile World Congress this week to show off its latest lineup of own-brand Android devices. There are three altogether — called the Lumo, Nivo, and San Remo — and like the company’s previous own-brand devices, they’re midrange and entry-level devices aimed at budget-conscious consumers who want a modern Android smartphone.

Two of them are particularly interesting: The San Remo is Orange’s first large-screen smartphone, packing a 4.7-inch IPS LCD display; while the Lumo is its first to boast speedy 4G LTE connectivity.

We went hands-on with all three devices to see if they’re any good.

BARCELONA, MOBILE WORLD CONGRESS — Sony’s initial unveiling of the Xperia Tablet Z came just after CES back in January, so Mobile World Congress here in Barcelona this week is the first chance we’ve had to get our hands on it. On paper, the device is very impressive, featuring a speedy quad-core processor, a high-resolution display, and a sleek form factor that measures just 6.9mm thick and boasts water resistance.

But specifications aren’t everything; we were itching to find out what the Xperia Tablet Z is like, so we went hands on with it this morning to find out.

BARCELONA, MOBILE WORLD CONGRESS — Thanks to the original PadFone’s rather disappointing start, we thought the probability of seeing a successor at Mobile World Congress was slim at best. But we couldn’t be more wrong. Asus has just unveiled the PadFone Infinity, a 5-inch smartphone that transforms into a 10.1-inch tablet with the help of a clever docking station.

The device has some impressive specifications, including a 1080p display, a quad-core Snapdragon 600 processor, and a 13-megapixel camera. But do you really want a smartphone that transforms into a tablet? We went hands-on with the device to find out.

ZTE has teamed up with NVIDIA to deliver the world’s first “superphone” powered by a Tegra 4 processor. The company hasn’t revealed much about the handset yet, but we do know it’ll have 4G LTE connectivity, and that it will make its debut in China this summer.

Mobile World Congress is now just a few days away, but some manufacturers just can’t wait to show you their latest devices. LG just unveiled its new Optimus F7 and Optimus F5 smartphones — two midrange devices that offer 4G LTE connectivity, and Android 4.1.2 Jelly Bean out of the box.

Here are all the juicy details on them.
