A Codex User Says Controlling the Agent From a Phone Ate 10 GB of Mobile Data in About Two Hours

Description and use

A Codex Remote user on Android consumed over 10 GB of mobile data in about two hours due to repeated large git diff requests.

Problem

Codex Remote on Android repeatedly pulls large git diffs, consuming excessive mobile data.

Outcome

The repeated full-diff requests caused a 10 GB mobile data overage in about two hours, with no fix or backoff implemented.

Workflow

• 1. User initiates Codex Remote session from Android phone.
• 2. Phone connects to host (Mac/Windows) and requests full git diff.
• 3. Host sends large diff (~34 MB).
• 4. Phone reconnects every ~29–35 seconds, re-requesting the diff.
• 5. Data usage accumulates rapidly, reaching 10 GB in ~2 h.

Evidence

ChatGPT for Android, used as a Codex Remote for a session on a Mac, burned more than 10 GB of cellular data in roughly two hours; two phone screenshots seven minutes apart show about 470 MB gone.
