At launch, Samsung Galaxy S8 and S8+ will feature a crippled Bixby
In a statement provided today to Axios, Samsung confirmed that a full-fledged Bixby (including voice commands) would not be available on the Galaxy S8 from day one, instead arriving "in the U.S. later this spring" - no exact release date was given. Still, various Bixby features, including Home, Reminder, and Vision, will be on board when the S8 and S8+ start shipping.
For now, Samsung doesn't say why it chose not to include every Bixby feature on the Galaxy S8 and Galaxy S8+ out of the box. However, it's highly likely that the digital assistant (specifically Bixby Voice) needs some extra fine tuning before Samsung is truly happy with its functionality.
We're certainly looking forward to seeing what Bixby will (or won't) be able to do on the Galaxy S8 and S8+ once the two smartphones are released.
