The Android 4.2, JellyBean update will not be available for Nexus S or Motorola XOOM users.
This news was confirmed by Google's Jean-Baptiste Queru, who stated that both devices will remain running Android 4.1.2.
The reasoning behind the software not updating to the latest build of Android is due to the older hardware included on the Nexus S and Motorola XOOM.
There were already reports of Android 4.1 running slow on both devices, so updating to the newer build would not be the best idea.
The Android 4.2 JellyBean update finally rolled out to Nexus 4 pre-release users earlier this week.
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 has implemented similar software directly into the Android operating system that will detect any foul play coming from foreign programs.
