Remove a Google account on Samsung Galaxy Core I8260

If you bought yourself a new phone and are going to give the old one to your child, you need to remove your Google account from the phone so that the new user does not accidentally access your profile and disrupt 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.
You won't be able to access 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?
Go to the Settings section.
Select Accounts and backup.
Select Manage accounts and select the account to delete.
