What

Connect a physical Android phone via ADB from a Mac mini or VPS; the agent loop is: take screenshot → vision model identifies UI element coordinates → ADB sends tap/text → repeat. Reference grounding-model benchmark cited in source: gui-agent.github.io/grounding-leaderboard — Holo2-8B for commercial, Holo2-235B-A22B for research. Known failure modes: LLM-predicted coordinates often off; mobile keyboards hide form fields.
