Starting Android the rst time
When you rst turn on your tablet, you have the opportunity to activate your mobile data service, to sign into your
Google Account, and to decide how you want to use some Google services.
Welcome to Android!
The rst time you power on your tablet you’re welcomed to Android and invited to pick a language to work in and to
start setting up and using your tablet.

Activating your mobile data service
On some mobile data networks, you must activate mobile data service on your tablet before you can use it to connect
to the Internet. As soon as you touch Start on the Welcome! screen, your tablet starts the activation process.
If your mobile network doesn’t require activation, or if your tablet only connects to Wi-Fi networks, it skips this step and
prompts you to connect to a Wi-Fi network instead (see “Connecting to Wi-Fi networks” on page 51).
Then you can use that mobile data network Internet connection to sign into your Google Account and nish setting up
your tablet.
If you prefer not to activate you mobile data service now or if you are setting up your tablet in a location without access
to your carrier’s mobile network, you can touch Skip to set up your tablet using Wi-Fi instead: you’re prompted to
connect to a local Wi-Fi network. See “Connecting to Wi-Fi networks” on page 51.
You can activate your mobile data service later using the Settings app; see “Wireless & networks settings” on page 91.
Setting your location preferences
Google’s location service uses the Wi-Fi and mobile data networks near you to make your approximate location
available to your apps. This location information can make nding your precise location by GPS much faster; it can also
provide your location to apps when GPS isn’t available.
When you use Google’s location service, Google collects data about your location and local networks, without
associating the information it gathers with you or your Google Account, to improve the service.
You can also choose whether to use your location in your Google Search results and other Google services.
You can change these settings after setup; see “Location and security settings” on page 96.
Starting Android the rst time

Signing into your Google Account
You must sign into a Google Account to use Google Mail, Google Talk, and other Google Apps; to download apps from
Android Market; to back up your settings and other data to Google servers; and to take advantage of other Google
services on your tablet.
If you have backed up your Android settings using a Google Account in the past and you want to restore those
settings to your tablet, you must sign into that account now, during setup: If you sign in after setup, you can’t
restore your settings.
If you don’t have a Google Account, you can also create one.
When you sign in, you’re prompted to enter your username and password, using the onscreen keyboard. For
information about navigating the touchscreen and entering text, see “Using the touchscreen” on page 13 and “Entering
and editing text” on page 39.
If you have an enterprise Google Mail account through your company or other organization, your IT department may
have special instructions on how to sign into that account.
When you sign in, your contacts, Google Mail messages, Calendar events, and other information from these apps and
services on the web are synchronized with your tablet.
If you don’t sign into a Google Account during setup, you are prompted to sign in or to create a Google Account the rst
time you start an app that requires one, such as Google Mail or Android Market.

Resetting your Google Account password
›
If you have a Google Account but forget your password, you must reset it before you can sign in.
Go to www.google.com, click Sign In, click “Can’t access your account?” in the sign-in box, and then follow the
instructions for resetting your password.
Additional accounts
›
After setup, you can add Google and other kinds of accounts to your tablet, and sync some or all of their data, as
described in “Accounts” on page 79. However, only the rst Google Account you sign into is backed up to Google
servers. Some apps that only work with a single account display data only from the rst account that you sign into.
Backing up and restoring your data
You can back up your settings and other data with your Google Account, so if you ever replace your tablet, you can
restore your data on the new one. If you choose to use this service, your data is backed up automatically.
If you previously used the backup service with the Google Account you just used to sign in, you can also choose to
restore your settings from your Google Account to your tablet now.
If you want to restore your settings, you must do that now during setup. You can’t restore data after setup is
complete.
Starting Android the rst time
10
Many kinds of data are backed up, including:
●
Your Android settings, such as your Wi-Fi networks and passwords, user dictionary, and so on
●
Many Google application settings, such as your Browser bookmarks
●
The apps you download from Android Market
Some third-party apps also make use of the backup service, so if you reinstall one, its settings and data are restored.
You can change your backup settings after you nishing setting up your tablet, see “Privacy settings” on page 101.
Finishing setup
If you aren’t connected to a mobile network, you’re prompted to set the date and time on your tablet. See “Time and
date settings” on page 106.
Otherwise, when setup is complete, Home opens, displaying your main Home screen.
To learn more about Home and the basics of using Android, see “Home and Android basics” on page 12.

Home and Android basics
Once you’ve nished setting up your tablet, Home opens. It’s a good idea to become familiar with the basics of
your tablet and how to use it—Home and its Home screens, the touchscreen, securing your tablet, monitoring and
responding to status and notication messages, and so on.
Getting to know Home
After you nish setting up your tablet, Home opens.
Home is your starting point for all the features of your tablet. You can use the Customize button

Double-tap ●: Tap quickly twice on a webpage, map, or other screen to zoom. For example, you double-tap a section of
a webpage in Browser to zoom that section to t the width of the screen. Double-tapping after pinching to zoom in
some apps reows a column of text to t the width of the screen.

Pinch
screen at once and pinching them together (to zoom out) or spreading them apart (to zoom in).
●
Rotate the screen
: On most screens, the orientation of the screen rotates with the tablet as you turn it. You can turn
this feature on and o, as described in “Screen settings” on page 96.
Using the Navigation buttons
The System bar’s Navigation buttons make it easy to quickly switch among Android apps.
In some media apps, the System bar controls are replaced by dim dots when you’re watching a movie, slide show, and
so on, so you can better enjoy them without the distraction of the System bar. You can touch a dot as it if were the
control it stands for, or touch a blank area of the System bar to restore it to full view.
