I have three Samsungs in my house. The one thing I hate is Bixby. It turns on when you don’t want it. It took over my daughter’s microphone, so she couldn’t make phone calls. It was a nightmare to get it back. (Many webpages on this problem). I’d love to get a Sony Experia for the best camera.
Galaxy S8 here. I disliked Bixby from the very beginning and found a way to disable it. I can’t even swipe to the page now and the left side button doesn’t bring it up. I don’t remember exactly how I did it.
I was also able to disable the “swipe up” function that brings up a “frequently used” page of icons from below the main home page.
