Bixby is Samsung’s very own virtual assistant which was introduced together with the Galaxy S8/S8+ and it’s also available on the Galaxy Note8. Not only you can command your phone using your voice, you can use it to set customised actions such as running multiple apps or tasks at a single command.
It also gets smarter the more you use it. If it doesn’t get it right the first time, you can teach it so that it will know how to respond the next time you issue the same command.
To encourage more people to use Bixby, Samsung is running a Bixby Level Up campaign where you can get rewarded with Samsung Reward points.
