Samsung's Bixby isn't exactly the most popular voice assistant, which is why some Galaxy Note 9 owners have been frustrated by the inclusion of a Bixby button on their handset. One tap would bring up the voice assistant, often by accident, and there was no way to disable it. Now, according to Android Authority, the new Note 9 software, which rolls out today, gives users the option to launch Bixby with a double tap, rather than a single tap.
