How to Turn Old Android Phones into AI Agents (Complete Guide)

What if that old device in your drawer could be transformed into a functional AI agent — capable of executing tasks autonomously? Thanks to emerging open-source tools like OpenClaw, Droidrun, and cloud services like Mobilerun.ai, this idea is now real. You can turn a forgotten Android phone into an intelligent automation node that executes workflows, interacts with apps, scrapes data, and acts as a personal AI assistant.
