The Nexus 4 and 10 come with 4.2 installed. For those with other devices, including the Nexus 7, you will need to download it if you want the new software on your device.
After downloading, you will need to manually install 4.2 onto the device. There’s an auto-update coming shortly, though, if you are willing to wait.
Will Andriod 4.2 Work on My Device?
There are a few prerequisites before you can install the new Jelly Bean onto your computer.
The first is that only the Nexus 7 and the Google Galaxy Nexus can currently receive the update, and the nexus 7 must have Android 4.1.1 installed, which is the software that originally came with the tablet.
Waiting for the automatic update is the safest and easiest way to get Android 4.2 on your computer.
New Jelly Bean: Do You Need It?
The original Jelly Bean already offered a number of benefits for users and may be enough for some. However, the new Android software on the Nexus 4 and Nexus 10 is perfect for those with many users on the same device who want to personalize their settings and for those who want more by doing less. Once Android 4.2 is widespread, there will be little support for previous versions and no updates, so it is worth getting it once it’s available on your device. The question many have is whether to get the update now, or wait for Google to organize it. That is something only you can decide.
