Using Shelly to give ChatGPT Codex remote control of an Android phone

On October 28, 2026, a developer tutorial on DEV Community described how to let ChatGPT's Codex mode take remote control of an Android phone. The whole setup runs on the phone itself. First, install Shelly, an open-source Android terminal, and grant it full file access. Then start the official codex remote-control command inside Shelly to obtain a pairing code. Finally, add that remote machine in the ChatGPT app. Once paired, Codex can run commands and phone-app tasks on the device. The tutorial stresses that every phone action waits for the user's approval on the phone before it executes, and that the setup needs no PC, no Termux, and no root. The author notes that a ChatGPT subscription is used rather than an API key. For hardware, the author develops on an arm64 Android phone, specifically a Galaxy Z Fold6, and states that other devices have not been verified. No test results are given for other models or Android versions, and the post covers setup steps and requirements only, without benchmarks or evaluation of stability and real-world performance.
