We can determine which version of Kindle Fire you have by the first 4 characters in your device's Serial Number. You can find your device's serial number by following these instructions:
- Start from the device's home screen.
- Click the Gear icon to bring up a ribbon of some settings. The option we need isn't there, so click the More option in the ribbon.
- You should now be in a full Settings screen. Click the option labeled Device (you might have to scroll the screen up or down to find it).
- In the Device screen, look for an option labeled Serial Number. It is 16 alphanumeric characters. Copy down the first 4 characters and let us know what they are. We can use those characters to determine which version of Kindle Fire you have.
