Bixby. although it is somewhat a clone to what the google assistant is, it trumps and does a LOT more than was Google assistant, or even Siri can do. think of it as a bit of Tasker, mixed with an assistant, that doesn't need full root permissions. From custom commands to full contextual actions. It's good for what it is, but you just have to talk to your phone a lot... I'm a doer, so i usually do all of these, or set up profiles/tasks in tasker to get it to do what i want automatically
