Many sites are showing users how to change from Chinese to English but you can't read the Chinese and the newest Fire 7 is not categorized like older versions in settings. Here is the solution.
Click your settings icon on the homescreen and you will be on this page:
Scroll to the bottom of this page and click the 3rd from the top which is Device Options.
On this page you will find your Keyboard and Language. Click the World icon
From this screen click on the first item in the list...Languages
On the final screen, you must first click the drop-down arrow to change it back to the desired Language.
Hope this helps anyone using the new Kindle Fire 7.
