The app buttons at the bottom of the newest Fire TV Remotes and Fire TV Smart TV remotes can either be fantastic or useless. They’re great if it’s an app that you use often, but they’re a complete waste if you don’t even have the app that they’re for installed. This guide will show you how to reassign the app buttons to open any app you want. This method uses my Remapper app and works for Netflix, HBO, Hulu, PS Vue, Disney+, CTV, Crave, DAZN, TVNOW, and other buttons. It works on the new remote paired to a Fire TV, Fire TV Cube, and Firestick, as well as Fire TV Edition devices from Element, Toshiba, Insignia, Onida, Grundig, JVC, and more.

UPDATE: Amazon has made changes to prevent my original remapping method from working. I have updated this guide with a workaround that should circumvent Amazon’s changes. If you previously installed any Remapper, it is best to uninstall it and carefully follow this guide from the very beginning. Enjoy this workaround while it lasts, but you should expect that Amazon will likely block it as well eventually.
UPDATE #2: The original workaround did not work on Fire OS 7 devices. The guide has been updated again to now work on all Fire OS versions. Read more ›
