Why do I need a Google™ account?
Your Xperia™ device from Sony runs on the Android™ platform developed by
Google™. A range of Google™ applications and services is available on your device
when you purchase it, for example, Gmail™, Google Maps™, YouTube™ and Google
Play™, the online store for downloading Android™ applications. To get the most out
of these services, you need a Google™ account. For example, a Google™ account is
mandatory if you want to:
•
Download and install applications from Google Play™.
•
Synchronise email, contacts and the calendar.
•
Chat with friends using the Hangouts™ application.
•
Synchronise your browsing history and bookmarks.
For more information about Android™ and Google™, go to
Follow the registration wizard to create a Google™ account, or sign in if you
already have an account.
You can also sign in to or create a Google™ account from the setup guide the first time you
start your device. Or you can go online and create an account at
www.google.com/accounts
