Remove a Google account on Samsung Galaxy A9 Pro (2018)

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).
