At a Samsung event in London last week, executives demoed the company’s new take on AI assistants. The headline news is that Gemini has effectively replaced Bixby as the default Galaxy phone AI, even kicking the latter out of the quick-launch home button.

Samsung unveiled its latest Galaxy S25 series of phones with an array of AI features. The modest hardware updates in these flagship phones show a growing emphasis on internal capabilities over external design.

The Galaxy S25 is a tale of two AIs: Gemini and Bixby. Yes, while Google's Gemini AI assistant sits at the forefront—it can finally be triggered through a long press of the power button—Samsung is bringing its original Bixby voice assistant out from the shadows.
