My last name has changed since I first had my gmail account. I've changed everything to my new name on my gmail and my google account but when I send email it still displays my old name. How do I change that?
Welcome to Android Central! Open your Email app, tap Menu>Settings, select the email account, and look for a way to edit the server settings. There's usually a field for your name as you want it displayed, which you should be able to edit.
