Remove a Google account on Samsung Galaxy S5 CDMA

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?
Emails, all data and content, including files and photos, will be deleted.
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?
Open the Settings app on your phone.
After that, select the menu item Accounts and backup.
Select Manage accounts and select the account to delete.
