Samsung’s newest foldable phones—the Galaxy Z Flip 8, Galaxy Z Fold 8, and Galaxy Z Fold 8 Ultra—are the first Galaxy phones to run Google’s newest on-device AI model, Gemini Nano 4, and the first to ship with One UI 9.0 and Android 17 out of the box. Google unveiled its Gemma 4 models earlier this year, which became the foundation for Gemini Nano 4, and confirmed on the Android Developers Blog that these three devices run the model. This allows AI features to operate entirely on-device without an internet connection. Gemini Nano 4 supports more than 140 languages, improved multimodal inputs including better text recognition in images and chart reading, stronger reasoning for logic and chain-of-thought tasks, and a larger context window. It is up to four times faster, uses up to 60% less battery power, and offers better support for agentic AI. The model also powers Gemini Intelligence features on the three devices, enabling automation of tasks such as booking concert or movie tickets, making a hotel reservation, or ordering coffee. Gemini Notebook also uses Gemini Intelligence.
