The new AI player was initially in line to debut on the South Korean giant's flagship smartphones after being unveiled last month, though will now be made available as an update this spring.
"Key features of Bixby, including Vision, Home and Reminder, will be available with the global launch of the Samsung Galaxy S8 on 21 April," the company said. "Bixby Voice will be available in the US on the Galaxy S8 later this spring."

Bixby is Samsung's swing at Apple's Siri, Google's Assistant and Amazon's Alexa, though there does appear to be some slight differences. Bixby will seemingly work primarily as a voice-based interface for app shortcuts, instead of just something you'll ask for weather updates.
When Bixby does eventually make its way to a future Gear smartwatch, we'd expect Samsung to have made headway with getting big name third party apps on board. This kind of time-saving integration is something we've already seen from Google.
Currently, no reason has been stated for the delays, though hints were already dropped during its launch that a day-one Bixby wasn't going to provide the full package. Samsung described it as the "first step", while also detailing an SDK kit that was set to drop at a later date.
It's also unclear where this leaves the plans for the voice assistant's debut on the company's range of wearable and smart home devices. A Samsung rep recently told Wareable that Bixby is coming to Gear watches but there's no roadmap for this rollout, which is probably a sensible course of action considering the delays it's facing.
Still, with the Gear S4 likely to drop later this year, it would be a surprise if the company hadn't resolved issues by then. Expect to hear of more developments regarding ol' Bixby in the coming months.
