Bixby isn't exactly finished yet, but Samsung has already dedicated an entire hardware button to it on its latest flagship handsets. As expected, most people didn't like that much and they complained about Samsung not giving them the ability to remap the button to say the camera, or ideally, the fully functional Google Assistant. The situation was remedied when a XDA Developer released an app onto the Google Play Store that allowed the user to remap the button to his/her liking. This time around, it was Samsung who patched it up and made sure that the app would no longer work after downloading and installing their latest OTA update which also includes the April security patch. At this point, it was believed that the S8 and S8+ will be stuck with Bixby on that button forever, unless you decided to root your device.
Apparently, that belief system was flawed since Redditor Dave Bennet has just releaed an application named BixRemap which does one better over Samsung. However, this time around, the app can only be used to launch Google Assistant instead of Bixby and nothing else. It is still a better option for the button rather than calling up Bixby which doesn't even work with voice commands yet. The user will still see Bixby beginning to launch on pressing the button, but the Google Assistant will replace it in a flash to come up instead. No rooting is necessary to use the app and it can now be downloaded from the Play Store. This app may not be as good as the previous release, but at least this one still works!
