The first time you open a Google application on your phone, you will be required to sign in with your existing Google account. If you do not have a Google account, you will be prompted to create one.
Creating your Google account
1 Tap Home > App Drawer.
2 Tap Settings > General tab > Accounts & sync > Add account > Google > Create a New Account.
3 Enter your first and last name, then tap Next.
4 Enter a username and tap Next. Your phone will communicate with Google servers and check for username availability.
5 Enter your password and tap Next.
6 Follow the instructions and enter the required and optional information about the account. Wait while the server creates your account.
Signing into your Google account
1 Tap Home > App Drawer.
2 Tap Settings > General tab > Accounts & sync > Add account > Google.
3 Enter your email address and tap Next.
4 Once you have set up your Google account, your phone will automatically synchronize with your Google account on the web (if a data connection is available).
After signing in, your phone will sync with your Google services, such as Gmail, Contacts, and Google Calendar. You can also use Maps, download applications from Play Store, back up your settings to Google servers, and take advantage of other Google services on your phone.
IMPORTANT
Some applications, such as Calendar, work only with the first Google Account you add. If you plan to use more than one Google Account with your phone, be sure to sign into the one you want to use with such applications first. When you sign in, your contacts, Gmail messages, Calendar events, and other information from these applications and services on the web are synchronized with your phone. If you don’t sign into a Google Account during setup, you will be prompted to sign in or to create a Google Account the first time you start an application that requires one, such as Gmail or Play Store.
If you have an enterprise account through your company or other organization, your IT department may have special instructions on how to sign into that account.
