Reports indicate that Samsung will delay the English-language version of its first voice-assistant app instead of launching it simultaneously with the Galaxy S8 smartphone on April 21. The app is named Bixby.

The Wall Street Journal credits "people familiar with the matter" with the discovery. These sources also tell the WSJ that Bixby's English version could be delayed until as late as "the end of May." That estimate was not based on a "final" decision, the report warns. No information was given about when other language versions of Bixby should be expected to launch.

Samsung's major March unveiling of the S8 had mostly been spoiled by leaked images of its handsome, tiny-bezel design. Early leakers pieced together clues about the S8's extra, unexplained button being connected to a voice-assistant service called Bixby. That late-March presentation confirmed the rumors by explaining how integral the Bixby service will be to the S8 (especially since it got its own dedicated button, as opposed to the voice-activated prompts used in comparable iOS and Android offerings).

Bixby was also inactive during our hands-on time with the phone at the late-March event. We were only able to see new "Bixby cards" in our demo, which displayed information that Samsung thinks users will want to pull up on the fly. These cards include personal fitness and local weather data. We will have to see whether the Bixby button revolves around these contextual cards before its voice-assistant features go live for English speakers.
