LG has received a lot of criticism for its Nexus 4 production rates in recent months. Since the handset went on sale last November, it’s been incredibly difficult to get hold of for the vast majority of would-be customers. Google Play stock doesn’t appear to be getting replenished as often as it should, and when it does, it’s sold out within just a few hours.

From LG’s point of view, however, Nexus 4 production is proceeding exactly how it was planned. The Korean company denies there is a supply issue, leading many to question how many handsets Google actually ordered.

Google has begun rolling out its latest Android 4.2.2 Jelly Bean upgrade to the LG Nexus 4. The software is currently reaching handsets located in Brazil and Malaysia, according to reports, but it’s likely it will also appear in other countries relatively quickly. Unlike Android updates for third-party handsets, Google’s don’t have to go through carrier testing.

This year’s Consumer Electronics Show has already seen the unveiling of several impressive Android handsets, including the Sony Xperia Z, the Huawei Ascend D2, and the Pantech Discover. But we haven’t quite seen them all yet. Lenovo just announced a new smartphone of its own, and it’s quite a looker. Equipped with a 5.5-inch 1080p display, the K900 is yet another “phablet,” but unlike the rest, this one’s equipped with an Intel Atom processor.

So, you’ve upgraded to the LG Nexus 4 and you have an old Samsung Galaxy Nexus kicking around that you no longer have a use for. You could sell it — the device still does well on eBay, despite being more than a year old — or you could hold onto it until late February when you’ll be able to get your first taste of Canonical’s brand new Ubuntu platform for smartphones.

Announced at CES 2013 in Las Vegas this week, Ubuntu for smartphones is coming to do battle with Android and iOS, and its first image will be for the Galaxy Nexus.

Apple and Samsung are the only two smartphone manufacturers currently seeing any growth in the United States. The pair are slowly eating away at the market share held by their rivals, including LG, Motorola, Research in Motion, and HTC. In the three months leading up to November 2012, Samsung increased its market share from 25.7% to 26.9%, but Apple is catching up with the Cupertino company enjoying slightly more growth.
