To access your email, contacts, and calendar, and to get apps from the Google Play Store, you can add accounts to your phone. When you add a Google account, info associated with that account automatically syncs with your phone.

When you remove an account, everything associated with that account is also deleted from your phone. This includes email, contacts, and settings.

2. Tap Passwords & accounts. If you don’t see “Accounts,” tap Users & accounts.
3. Under “Accounts for,” tap Add account.
4. Tap the type of account you want to add.

   • To add a different personal account, tap Personal (IMAP) or Personal (POP3). You’d generally choose these if you use an email program like Microsoft Outlook or Apple Mail.
