Bixby is a major feature in the new Galaxy handsets that Samsung is betting on to gain consumer trust after the Note 7 debacle. Home, Vision, and Reminder would be available to the users from the day of launch, but the Bixby voice won't be available to the users until Spring 2017.
During tests, the performance of English Bixby has lagged behind the Korean version, which explains why Samsung doesn't want to release it yet. One of the main focus during Samsung's Unpacked event for the Galaxy S8 and Galaxy S8 Plus last month was its own virtual assistant called Bixby.
Samsung confirmed that voice control would not be ready in time for the Galaxy S8 launch in a statement to The Verge.
However, some of the apps created to work with Bixby will still feature on the phone including Vision, which lets you point a camera at objects in the real world to use augmented reality and see information on your phone screen.
The company did not give an explanation for the delay.
Despite this, the Samsung Galaxy S8 will arrive with all of Bixby's other features, except for the most important one - voice control.
Samsung added: "When an application becomes Bixby-enabled, Bixby will be able to support nearly every task that the application is capable of performing using the conventional interface (i.e. touch commands)".
Speaking to Silicon, a Samsung spokesperson said: "All Bixby functionality, bar the Voice Function, will be available to United Kingdom customers at launch".
Samsung proudly touted the new smart assistant during the launch of the new smartphone.
Samsung told Express.co.uk that the feature will be pushed-out to UK Galaxy S8 owners later this year.
