Google just released its updated changelog for Android 4.2 Jelly Bean and pinpoints which features are improved upon from the Android 4.1 Jelly Bean build. The release of the Android Jelly Bean 4.2.2  to Nexus devices last week raised questions about the whereabouts of a changelog.

Users were uncertain exactly what features were new or revised in the over-the-air OS update. As they might with a puzzle, Android users pieced together bits of information about changes noticed in the update.

Some immediately noted changes found by the Android community were the Bluetooth fix and a couple of new toggle buttons. Additional changes to the system were found to be an alternatively styled download progress bar and the addition of a few new system sounds. As Google gradually rolled out the Jelly Bean 4.2.2 update to Nexus devices, users noted other minor changes as they were discovered.                                                                                                 

As listed in the official Android 4.2 Jelly Bean changelog, "Android 4.2, Jelly Bean improves on the speed and simplicity of Android 4.1 and includes all new features - Photo Sphere and a completely redesigned camera app, new Gesture Typing keyboard, Google Now with all new cards, and much more."

Under the "accessibility" setting users can enable "magnification gestures" and can enter into full-screen magnification by triple-tapping the device's screen. From the power menu, users can enable the "TalkBack" feature. For an enhanced photography experience, users can enjoy a redesigned camera with new tools, a new photo editor, Photo Sphere for taking 360-degree images and access to the camera from the lock screen.

Widgets can now be added to the lock screen for quicker access to important apps, and Google Now can be accessed from the lock screen with one swipe gesture. Numerous features were added to Google Now, making it more efficient for obtaining real time information on travel, directions, stocks and entertainment.

The latest over-the-air update was released without an official changelog and one can only speculate what the reason was for the delay. Perhaps Google intended to wait until a majority of users received the Android 4.2 Jelly Bean updates for their devices?
