No remapping of the Bixby button on Samsung Galaxy S8, S8+
As you already know, one of the biggest selling points for Samsung’s latest flagship device is its an AI-powered digital assistant Bixby.
According to XDA, Samsung released an OTA update which blocks users from remapping the Bixby button. As the Bixby button is reportedly no longer routed through the accessibility service, users will have to root their devices to remap the button to a non-Bixby app.
