What is "Android 4.2"?

Android 4.2 (AKA, Android 4.2 Jelly Bean) is the first major update to the Android 4.1 Jelly Bean build, released on November 13, 2012. As part of the Jelly Bean family and arriving just months after Android 4.1, this build offered more measured improvement over the Android 4.1 experience. One major change came in the lock screen, which Google made much more functional with the addition of widgets and the ability to swipe directly to the camera. Other changes included a new clock application with world time and stopwatch, and a larger list of actionable notifications.
