Included with the update is the feature that shows video highlights from your photo gallery, and the usual Android 4.2.2 additions like Daydreams and lock screen widgets. The update also brings improvements to the phone's battery life.
The update is 484MB which means that you might need a C-section to birth it. Seriously, this is a rather hefty update that for now is being rolled out for unlocked units in Asia.
