Bixby is Samsung's new virtual assistant similar to Siri or Amazon Alexa. Users can ask it questions, get driving directions, check the weather and much much more. Sadly the voice controls of this digital virtual assistant aren't yet available.
However, that isn't the exciting part. Bixby also works inside the camera. It's called Bixby Vision. Open the camera on your Galaxy S8 and you'll se a notification for Bixby. Once this is pressed Bixby can scan images using the camera and do some pretty incredible things. Like find an item and let you buy it, give you facts about a landmark, scan QR codes, or even translate languages and words in real-time. It's pretty powerful, but you'll need to try it to fully understand how great it can be.
Just know the camera has some pretty magical features.
