Review: Samsung Galaxy Note 9For Galaxy Note 9 users who have no use for Samsung’s Bixby assistant, you might want to completely disable the Bixby button. Unfortunately, that option isn’t available on this phone. But a new update coming to Bixby will at least make it harder to accidentally activate the button. It’s quite easy to accidentally launch the assistant because its button is placed under the volume rocker.
Once you have the latest update, you can head to Bixby’s settings and select whether you want to launch the assistant by a single press or with a double tap. The latter lessens the chances of you accidentally launching Bixby since you’ll need to hit the button twice in rapid succession. If this is something you want and aren’t sure if your Bixby is updated, head to Settings > About Bixby and tap on the Update button.
