How AI Agents Control Smartphones

AI agents operate on top of an LLM to achieve specific outcomes rather than just generating answers. A smartphone-controlling agent observes the device state, selects actions based on goals, executes them via authorized paths, and verifies results. This differs from AI phone assistants, which may only invoke specific app functions. For developers, understanding LLMs is the foundational step in building these systems, as agents interpret screens and revise steps to navigate cross-app controls effectively.
