Android Jelly Bean 4.2 is an incremental upgrade over Jelly Bean 4.1, but it includes some useful new features - notably, the ability to set up multiple user accounts. This enables the Google Nexus 7 and Nexus 10 Android tablets to become true family PCs, offering unique working environments for every member of the household.
How to set up user accounts on the Nexus 7, Nexus 10
You can set up individual user accounts that are complete with their own homescreen, background, widgets, apps and games, and you don't even need to log in and out to switch between them. Do note, however, that any user can accept updated app permissions or meddle with wireless and other settings on behalf of all users - you might want to set down some ground rules here. See Best Android Apps.
Here, we show you how to set up user accounts on the Google Nexus 7 and Google Nexus 10 (this feature is not available on the Google Nexus 4).
How to set up user accounts in Android Jelly Bean 4.2
Step 1. Drag down from the top right of the screen to access Jelly Bean's Settings menu, then tap Users in the left panel. You will be shown as the Owner, and if you like you can also set a nickname and, under Owner info, enter text that will appear on the lock screen. Tap the icon next to the Owner field to access your profile, in which you can add a photo and information such as your phone number, email address, notes and so on.
Step 2. To add a new user account for another family member, tap Add User at the top right of the screen. A message will pop up informing you what privileges will be available to the user; tap Ok to continue. Note that the family member will need to be present to set up their account - tap 'Set up now' only if they are available, otherwise choose Not now.
Step 3. You'll be returned to the lock screen, which now features two icons for user profiles. The icon for the new user profile is slightly larger, signifying that this user is currently logged in. Drag your finger across from the lock icon to unlock the tablet and begin customising the new user proile.
Step 4. Jelly Bean 4.2 will guide you through a setup routine on the Nexus 7 and Nexus 10. Tap the triangle at the bottom of the screen to skip the Welcome message, then enter the new user's Google account details. If they don't have one they can sign up now, or you can tap Not now to do so later. Note that they will need a Google account to download and install their own apps, but if it is a child whose profile you're completing, for example, you may prefer that they don't have individual access to Google Play.
Step 5. On the next screen decide whether you want Google and third-party apps to be able to access your location using Wi-Fi and GPS. The default for these is that they are enabled, but you can change these options at any time in the Settings menu.
Step 6. Enter a name for the new user and, finally, agree to Google's terms. The new account is now ready to use.
Step 7. Upon opening the new user account, you'll be presented with a familiar view: your Nexus 7 or Nexus 10 home screen looks exactly as it did before you began making yourself at home on the tablet, installing apps, changing wallpapers, adding widgets and so on. Any personalisation you complete in this environment will not affect the Owner or other user accounts, but app permissions and settings such as Wi-Fi are universal.
Step 8. As before, you can add a photo to the profile by dragging down from the screen's top right and choosing Settings, Users and tapping on the icon next to the account name.
Step 9. There are two ways in which to switch between user accounts on the Nexus 7 and Nexus 10. First, from the lock screen, simply tap the icon for the user profile you want, then drag the lock across to access the tablet. Alternatively, if the tablet is already in use, drag down from the top right of the screen and click on the user profile to be taken to the lock screen.
