According to a report by SamMobile, the Bixby button can be reprogrammed to do something other than just opening Samsung's brand new AI assistant Bixby. In spite of Samsung's constant advertising of Bixby, the truth is that it can't really do much that the Google Assistant can't do already and better. There's of course the image recognition capability where if you click a picture of an object, Bixby shows you multiple options to buy it online, but that's practically the only significant feature that's unique. We will have to wait and see what other features Samsung brings to the software with updates of course. In the meanwhile, if you are satisfied with using Google Assistant and you would like the hardware button to be used as a shortcut to something else like the camera or your favourite app, people have actually found an unofficial way to do so.
You will have to download an app from the Google Play Store called All in One Gestures. There's even a convincing video on the entire process and you will find it below. We were disappointed when Samsung did not give us the option to change the button mapping by default and frankly, that made no sense from the point of view of the consumer. However, we are happy that though it will require a third party application, at least it can be done!
