09. How to update the Android OS on your Nexus 7
The Nexus 7 comes out of the box with the latest version of Android, codenamed Jelly Bean (v4.2). It's one of the only Android tablets to have 4.2 so far, but that doesn't mean it won't be receiving more updates in the near future!
Once a new update becomes available for your Nexus 7 you should see a new notification appear to inform you of the update and to give you the option to download it. This is fairly straightforward and only requires you to have enough battery life to last the length of the download and install process. If, however, you are expecting an update and haven't seen a notification, there is a way to manually check for new software versions.
Place your finger in the top right-hand corner of the tablet and slide it downwards so that you can see the settings panel.
Touch the Settings icon and scroll down to the very bottom of this list.
Once you reach the end of the Settings menu, touch the About tablet option.
On this new page, you should notice the very top entry on the list is called System updates. Press on this entry and wait for a few seconds whilst the Nexus searches for any new software updates.
One thing to be aware of when searching for updates is that only the owner of the Nexus 7 can find and install new versions of the operating system. If you can't see the Software updates entry, you may be signed in as a guest account. Lock the tablet and select your owner's account when turning it back on to be able to search for new updates.
Hey presto - you're up to date.
