When I first got my Galaxy Tab Pro I set up my Google account. Since then I've changed my google id and password. But I can't figure out how to change the way it's set up on my tablet. On my Galaxy phone it let me delete the Google account. So I just deleted the old one and then added it back with the new id and password. But I see no option on my tablet to delete the Google account I originally set up, or any option to change the id and password it uses. This is so simple and yet so frustrating that I can't figure out how to do that. Can someone help please?
