Could this be the Bixby logo?
Samsung has filed an application with the European Union Intellectual Property Office, that's currently under examination. The application is an attempt on Samsung's side to trademark a certain logo that looks like a stylized version of the letter “B”. The trademark application is similar to that of Bixby itself, so we do believe there is a connection between the two, and this is indeed what Bixby's logo will look like.
With Bixby being fluent in more languages than Google Assistant, one can tell that Samsung is betting a lot on that one card. All we can do now is just wait and see for ourselves if it pays off.
