BARCELONA, MOBILE WORLD CONGRESS — Here at Mobile World Congress, ZTE is showing off the Grand Memo, its new super-sized smartphone that packs a giant 5.7-inch display.

LG announced its super-sized Optimus G Pro last week, a 5.5-inch handset that’s coming to do battle with the Samsung Galaxy Note II. The device will be coming to Korea this week, the company has now confirmed, before making its way to North America during Q2 2013.

In addition to its impressive 1080p display, the Optimus G Pro will also be the first smartphone to offer a quad-core Snapdragon 600 processor, which is the successor to the popular Snapdragon S4 Pro.

A couple of days ago, Google started rolling out the Android 4.2.2 Jelly Bean update for the Galaxy Nexus, Nexus 7 and Nexus 10, with the Nexus 4 joining the list today.

Depending on your region and your luck, you might just be able to manually initiate the OTA update on your Nexus device. Here are the steps you’ll need to give it a go.
