Ex-Google engineer turns an old phone into an agent that finished 42 tasks overnight

A former Google Android engineer shows how to turn a drawer-kept phone into autonomous agent hardware using Grok Bot: a screen reader converts screenshots into buttons and fields, a tapper/typer operates apps like a human, and a checker catches errors (e.g., a wrong date) before sending. The phone worked overnight while charging from 19% to 100%, completing 42 tasks. His point: most people give agents a chat window, almost nobody gives them a whole phone. A build guide is linked in the thread.
