I'm not sure why people are so eager to disable the Bixby button. Why not just don't double tap it so that it won't activate Bixby? I know at the moment the software is not ready and installed yet, but why not just ignore it? If you like using Google now thankfully Samsung didnt remove or block it. Also if you like google now you should like Bixby when it becomes fully functional and perhaps with more features than GN. Remapping the button to use GN seems unnecessary to me, but that's just me, because GN already have the home button you can press. For me, I look forward to using Bixby.
