  • Do not map any action to single-tap for any button other than the App buttons. Doing so could compromise the functionality of your device. 
  • Be extremely cautious when mapping action to the D-pad and Volume keys. These buttons are designed for navigation and volume control. And we believe that double-tap and long-press are integral part of these buttons.

Points to remember after Remapping

  • The Button Mapper app was designed with Android smartphones and tablets in mind. And all these have in common are the few numbers of buttons. So the app might not display the exact names of some keys (or the actual button) of the Chromecast remote. For example, the Netflix button of the remote is having the name BUTTON_3, and it needs to be added manually to the list of keys.
  • The app comes with issues. Even though we mapped new tasks to some of the buttons like Youtube, the predefined action was executed along with the newly assigned ones.
  • Long pressing the Netflix button also yielded a similar result. It executed the new task while opening Netflix listing on the Play Store even if it isn’t installed. 
  • We recommend that you try out different combinations and go with the ones that are best suited for your usage patterns. Remember our warning about assigning actions to single-tap input.
  • The idea of remapping the keys is valid for other Android TV devices like the Nvidia Shield and Mi Box series.
