Android 4.2, JellyBean Update Rolls Out to Nexus 4 Pre-Release Users

The new Android 4.2 JellyBean update has finally rolled out to Nexus 4 pre-release users.

The Nexus 4 smartphone will now have the ability to upgrade to the latest version on Android 4.2, which brings features that Google has previously covered such as Lock screen widgets, and Multi-user support.

Lock screen widgets appear on the device's lock screen and allows the user to customize them in order to view their Calendar, email, and to also identify music with Sound Search.

Multi-user support is an interesting feature that allows Nexus 10 users to share their tablet with others by creating separate customizable spaces for each person. In order to log in, users can simply turn on their tablet and tap their photo and they will be able to access their own customized version of their homescreen, apps, email, photos, and storage.

Users can customize their homescreen by choosing a wallpaper, adding favorite apps and games from Google Play, creating folders, and arranging beautiful widgets by dragging and dropping.

A Google spokesperson confirmed to 9to5 Google that Nexus 10 and Nexus 4 users will be prompted to install the update once they power up their devices for the first time.

Google has also introduced a new security feature on Android 4.2, JellyBean that aims to reduce the running of malware on an Android device.

A similar software to this was released in the past with Bouncer, which was available in the Google Play store .

Bouncer checked applications in the Play store for malicious content.

Now Google is implementing similar software directly into the Android operating system that will detect any foul play coming from foreign programs.

The service will be checking sideloaded applications in particular, and even though Android does not allow users to sideload apps, this restriction can be removed by enabling the "Unknown sources" installation option from the Settings menu.

When this is enabled, Android users can install any application on their device, including malicious content.

The new security feature will check the application when it is being installed with a list on Google's server to see if it matches with any of the malicious apps out there.
