U.S. Cellular is the latest carrier to be rolling out the much-anticipated over-the-air updated OS version to all its Galaxy S4 carrier-branded smartphones. This hefty upgrade, which weighs in at 537MB, brings the latest build of Android 4.3 Jelly Bean together with support for the Galaxy Gear.

The LG G Flex — the curved-glass smartphone that really flexes — is coming to Europe next month after making its debut in South Korea. The device will be available in France initially, and you’ll need to start saving now if you want to buy it off contract, because it won’t be cheap.

Apple’s iPhone 5s became the world’s first smartphone with a 64-bit processor when it launched this September, but as you might expect, it’ll have plenty of competitors next year. Unsurprisingly, some of those will come from Samsung, which is already planning 64-bit chips and 16-megapixel cameras for its 2014 flagships, according to industry sources.

Sony has this week confirmed its Android 4.3 Jelly Bean and Android 4.4 KitKat upgrade plans for Xperia smartphones and tablets. If you have a recent, high-end Xperia device, then you’ll be eligible for both updates — and you can expect the first to start rolling out “from next month.”

Google is in the process of rolling out its much-anticipated update for its official Hangouts application which comes pre-loaded on all Android devices. This upgrade brings some interesting new features, including SMS & MMS integration, location sharing and animated GIF support.
