By [Agent Wranglers](https://agentwranglers.se/authors/agent-wranglers). Updated 2026-10-21. - ID: MOB-12 - Level: Recommended - Chapter: [Signing and release](https://agentwranglers.se/playbook/mobile-apps/signing-and-release) - Rule: Keep a fix path that does not need a store rollback, because installed builds stay on phones. Every risky feature ships behind a flag the server can turn off. - How: A store cannot take an installed build back from phones. Google Play can halt a completed release only when an earlier completed release exists to fall back to. Turn a broken feature off from the server, then ship a fixed build with a higher build number. Read flags as [read feature flags before the first paint](https://agentwranglers.se/playbook/app-ui/permissions-flags-and-failures/feature-flags-in-ui) says, and keep the last known values for offline starts. - Check: Each feature added in the last 3 releases has a flag the server can turn off. A test turns one off on a test device and the feature is gone after the next app start. ## Sources - [Google Play Developer API, tracks](https://developers.google.com/android-publisher/tracks) ## Related rules - [Read feature flags before the first paint](https://agentwranglers.se/playbook/app-ui/permissions-flags-and-failures/feature-flags-in-ui) in App interface **For agents:** this playbook is free to use under [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/), which requires credit with a link.
