I have used the camera's voice control on my Galaxy phones since Samsung first offered it. It's one of the first things I enable when I get a new phone. I know this shouldn't be a hard decision (knowing how people feel about Bixby) but I've discovered you can't have Bixby voice enabled and use the the camera's voice control. It's one or the other. Why? You're not saying "Hi Bixby" before saying shoot, or smile or cheese.
