Remove a Google account on Samsung G3812B Galaxy S3 Slim

If you are going to give your old phone to your child or another family member, you need to remove your Google account from your phone so that the new user does not accidentally delete important emails in your mailbox or disrupt other Google services.

What happens after deleting a Google account?
All data and content associated with the account will be erased, including emails, files, calendars, and photos.
The phone user will not be able to use Google services that require an account (such as Gmail, Drive, Calendar, or Google Play).
You will lose access to subscriptions and content purchased through this account on Google Play and YouTube (for example, applications, games, music, TV series).

How do I remove a Google account from my phone?
Open the Settings app on your phone.
Select Accounts and backup.
Select Manage accounts to access the accounts saved on your device.
