It’s much bigger than it looks.

Sony has unveiled its new Xperia Z Ultra phablet at the Mobile Asia Expo in Shanghai this morning. The device boasts a large 6.4-inch display, the latest Qualcomm Snapdragon 800 processor running at 2.2GHz, and 4G LTE connectivity. Like its little brother, the Xperia Z, the Xperia Z Ultra is also waterproof.

LG has confirmed that it will use Qualcomm’s latest high-end Snapdragon 800 processor in its next Optimus smartphone. The Snapdragon 800 is an upgrade over the Snapdragon 600, which is currently shipping inside the latest flagship smartphones, including the HTC One and the Samsung Galaxy S4.

Still trying to choose which flagship smartphone you’re going to pick up this year? Well, if display is the most important thing to you, the Huawei Ascend D2 currently has the best on the market, according to the experts at DisplayMate. Steer clear of the Sony Xperia Z, though, because that has the worst.

T-Mobile USA has confirmed that it will carry the Sony Xperia Z this summer, finally putting an end to all the rumors that have been circulating since the device was spotted back in April. The carrier will become the only provider in the U.S. to offer Sony’s waterproof smartphone, which has been available in Japan and Europe since January.

Prior to its unveiling back in March, the Samsung Galaxy S4 was one of the most anticipated smartphones of 2013. It has big boots to fill after following the hugely successful Galaxy S III, and to do that it’s been equipped with a new 5-inch 1080p display, a quad-core Snapdragon 600 processor, and an entire plethora of software features you won’t find anywhere else.

But is the Galaxy S4 worth the upgrade if you already have a Galaxy S III, and does this device have what it takes to stay one step ahead of its competitors? I’ve been using it for the past few weeks to find out.
