Samsung has had its fair share of flack about Bixby, mainly because nobody wanted another AI assistant - let alone one that's even more useless than the test of them. While Samsung initially wouldn't let people officially disable or remap the Bixby button when it launched on the Galaxy S8, it eventually (sort of) relented and let users turn the button off. With the launch of the Note 9, it seems to be back to its old tricks of forcing Bixby on a populace that really doesn't want it.
As noted by The Verge, the Note 9 is missing the settings menu that lets users turn off Bixby and its dedicated button - a setting that is currently present on the Galaxy S9, Note 8, and S9. Trying to search for 'Bixby Key' also comes up with zero results, unlike the Note 9's older brothers. Plus, once again Samsung isn't offering users a way to officially remap the button for something more useful.
As we mentioned in our review of the Note 9, Bixby has come a long way since it first launched 18 months ago. Unfortunately there wasn't enough time to see quite how much it's improved, and the general consensus among critics has been that it's still well behind the likes of Google Assistant. It's slightly funny that running the phone on Android also means Samsung has had to put Assistant on the Note 9 as well, making Bixby that extra bit pointless in the long run.
Fortunately there are still plenty of Bixby remapping apps out there, though the top-rated app on Google Play notes that there are still some features that aren't available with Bixby 2.0. So if you've bought a Note 9, be aware that those features are still a work in progress. [The Verge]
