An anonymous reader quotes a report from Washington Post: A much-touted feature of Samsung's next smartphones isn't going to work as advertised when the Galaxy S8 and Galaxy S8+ launch April 21. Samsung said it's delaying the launch of voice-command capabilities for its Bixby voice assistant in English, according to a report in the Wall Street Journal. Although some of its features will still work, the report said, Bixby -- Samsung's answer to Apple's Siri -- won't be able to respond to any user voice commands, perhaps until as late as May. The Korean-language version of Bixby will have all of its features at launch, the Journal report said. The reason this is a big deal is because Samsung has touted Bixby as a big new feature for the Galaxy S8. Not only is it baked into the software, but it features a dedicated Bixby button on the lefthand side of the phone. The new assistant is designed to "perform almost every task that the app normally supports using touch," according to PhoneDog. "It'll be able to understand the current context and the state of the app that you're in without interrupting the work that you're doing," and will be able to "understand commands with incomplete commands, meaning you don't have to remember the exact phrase that you have to say to perform a task with an assistant."
