A Wednesday news release from Samsung indicates that it's solved those problems and that Bixby will be able to do some fairly complicated tasks.
Users can, Samsung said, ask Bixby to do things such as "find photos I took in Spain and create an album called 'Vacation.' "
As good voice control becomes a major point of competition among tech firms, Samsung is under some pressure to show that Bixby can match or even go beyond existing voice assistants.
But it will have to overcome the perception that Bixby was dead on arrival - or, rather, on its lack of arrival when it launched with the phone.
Galaxy S8 and S8+ users have had their phones for months now, and those excited about using a voice assistant on their phones could use Google Assistant from the start.
Galaxy S8 and S8+ users in the United States and South Korea can start using the assistant's full English-language capabilities starting Wednesday, as soon as they download an update to the Bixby app on their phones.
