As a major feature in the Galaxy S8, with a dedicated button on the left side of the device, Bixby's absence could deter customers from purchasing Samsung's new smartphone. However, in a statement given to The Verge, Samsung admits that Bixby's headline feature - voice control - won't be ready in time for when the device ships to United States consumers on April 21.
Speaking to Silicon, a Samsung spokesperson said: "All Bixby functionality, bar the Voice Function, will be available to United Kingdom customers at launch".
Last year Samsung acquired U.S. artificial intelligence platform developer Viv Lab, a firm run by a co-creator of Apple's Siri voice assistant program.
Bixby enters a crowded field of digital assistants powered by artificial intelligence that includes Apple's Siri, Google Assistant, Microsoft Cortana and Amazon's Alexa. However, the company said in a statement that the Bixby Voice feature would be rolled out only in Spring.
The company did not give an explanation for the delay.
It seems Samsung is not having the start it wished for with the new flagship device Galaxy S8.
The Galaxy S8 and S8 Plus will be released commercially next week but sadly, Bixby will not be fully ready.
Samsung proudly touted the new smart assistant during the launch of the new smartphone. We also expect more Galaxy smartphones with Bixby support to launch later this year, including the Galaxy Note 8. Hopefully Samsung will be able to get Bixby Voice working quickly and that we won't be waiting until the end of spring for it to arrive. Some Bixby features will still work, and Google's Assistant will run on the handset.
The new smartphones have been proving a hit with Australians, with Samsung reporting they are selling more than the troubled predecessor Galaxy 7 by a rate of "double-digit percentage points".
