When Google released the latest version of their Android Jelly Bean OS which is version 4.2 in November 2012, only few devices were allowed to receive the update. Only Nexus devices have so far been entitled to come out with Android 4.2 whereas all the popular phones that were released at the end of 2012 and early this year have only come out with Android 4.1 or older version of OS.
When the Google I/O even took place last year, Google had unveiled the Android 4.1 Jelly Bean OS. At that time, the Android 4.1 was the most recent version of Android and it replaced the Android ICS OS which was released in December 2011. Most of the devices regardless of the brand name that were released after the Google I/O event were allowed to receive the Android 4.1 update.
When Android 4.1 released, nearly half of the Nexus devices that were available in the market received the update. The other Nexus devices could not receive the update at one go. In the month of September, Sprint and Verizon Galaxy Nexus received the Android 4.1 update. Soon Galaxy S3 and Asus tablet also received the same update. In the November, the update was made available to several popular phones including HTC One X and in the same month Google rolled out the Android 4.2 Jelly Bean.
The Android 4.2 was made available for Galaxy Nexus and Nexus 7 in quick succession after November. Google promised that the Android 4.2 update would be available for other devices but as of now many devices are still awaiting to get the update. Even the Verizon Galaxy Nexus is also yet to see any update from September.
In fact, many new phones of 2013 including HTC One are still going to be released with the same old Android 4.1 OS. The Galaxy S4 is believed to be out with Android 4.2 but still there is no confirmation on it. Sony’s Xperia Z is also expected to be out with Android 4.2. Some other devices were also showcased at MWC 2013 to run on Android 4.2.
