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.
