Samsung has introduced new Agentic AI features with Galaxy S26. Does anyone know what these are?

Samsung has launched new Agentic AI features with the Galaxy S26 series, but I’m not entirely sure how it actually works. I want to understand what these AI capabilities are, how they work in real use, and what benefits they bring to the phone experience. I’m especially interested in learning whether it improves other tasks, such as photography, productivity, voice assistance, or everyday phone interactions, compared to previous models.
