Summary

Codex Mobile setup appears to be stuck in a loop on Android/ColorOS because the QR code opens an unhandled link instead of being routed to the ChatGPT Android app.

Environment

  • Desktop app: Codex for macOS
  • Codex desktop version: 26.513.31313 (bundle version 2867)
  • macOS: 26.3 (25D125), arm64
  • Mobile device: OPPO Android phone / ColorOS
  • ChatGPT mobile app: 1.2026.125
  • Date observed: 2026-05-17

Steps to reproduce

  1. Open Codex desktop app on macOS.
  2. Start Codex Mobile setup from the desktop app.
  3. Select Android on the setup QR screen.
  4. On an OPPO Android phone, scan the QR code using the system scanner or Chrome QR scanner.
  5. Observe where the decoded link is opened.

Expected behavior

The QR code should open the ChatGPT Android app directly and show the authorization flow for allowing the phone to access Codex on the computer.

Actual behavior

The phone opens a browser/search page instead of ChatGPT. Chrome tries to load a URL beginning with:

https://com.openai.chat//codex/open

This URL is not one of the verified Android App Links currently shown for ChatGPT on the device. The ChatGPT app's verified links list includes domains such as:

platform.openai.com
chatgpt.com
www.chatgpt.com
chat.openai.com
www.chat.com
chat.com
tt.chatgpt.com

Because the decoded setup link is not handled by ChatGPT, the mobile app remains on the "waiting for desktop" screen, while the desktop app waits for mobile authorization. This creates a setup loop.

Additional notes

  • The full QR payload is intentionally not included because it may contain authorization/session parameters.
  • The user tried OPPO system scanning and Chrome scanning; both failed to route the link into ChatGPT.
  • Android system settings show ChatGPT is configured to open supported verified links in-app, but com.openai.chat is not available as a verified web link/domain.
  • This may be a mismatch between an Android App Link URL and an app custom scheme, or a ColorOS compatibility issue where the QR payload is interpreted as an HTTPS URL rather than a ChatGPT deep link.
