Remove a Google account on ZTE Blade A606

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.

All data and content associated with the account will be erased, including emails, files, calendars, and photos.
You won't be able to use Google services that require you to sign in to your Google account (such as Gmail, Drive, Google Play or Calendar).
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.
Click Manage Accounts and delete your account.
