Two of the most popular Korean operators, SKT and LG U+, are in the midst of pushing out an unexpected over-the-air (OTA) update to all Optimus G Pro handsets located in South Korea. In terms of functionality, the upgrade brings Android 4.4.2 KitKat and Sense 5.5 to the device, complete with the usual plethora of bug fixes, speed optimizations and stability improvements that we’ve grown to expect from any major software update.

A leaked soak test screenshot has been published on the internet revealing that AT&T’s much-anticipated Android 4.4.2 update for LG’s former flagship phablet of 2013, the G Pro, is currently in the final phase of development and should start rolling out by way of an over-the-air update very soon. It’s rumored that this upgrade ferries the latest build of KitKat, in addition to several enhancements for the company’s extremely unique user interface.

LG has confirmed that it will be unveiling its new G Pro 2 smartphone at Mobile World Congress in Barcelona next month. The original 5.5-inch Optimus G Pro made its U.S. debut last May as LG’s answer to large smartphones like the Galaxy Note, and it’s thought the G Pro 2 will be even bigger.

LG’s first high-end phablet, the Optimus G Pro, was announced back in February and has only been available to purchase from independent third-party retailers for the past couple of months, but as from today it’s now also available to buy from AT&T.

The LG Vu II, with its rather odd 4:3 aspect ratio, is one of the most unique Android-powered phablets on the market. And it’s likely to retain that title when the Vu III launches later this year, according to leaked specifications that have surfaced in Asia.

In addition to a 4:3 display, this time with a higher resolution, the Vu III is expected to offer the latest Snapdragon 800 processor, and LTE-Advanced technology.
