About this app
GMS Flags is an Android root/Xposed app that lets you view and override Google's hidden Phenotype configuration flags — the same server-controlled feature flags Google uses internally to gate in-progress features, A/B tests, and rollouts across Gboard, YouTube, Google Photos, Play Store, and the rest of the Google app suite.
With root access and Xposed/LSPosed, GMS Flags reads and writes these flags directly on your device, so you can turn on features before they officially ship, revert a change that broke something, or just see what a given app has stashed behind a flag.
Features
- Browse and search every Phenotype flag for a supported app, grouped by package. - Override boolean, int, float, and string flags, individually or in bulk. - Curated recommendations — flag combinations known to unlock a specific feature, with a one-tap apply/undo and an honest "does this actually work on your install" status check. - Signed micro-hooks (Needle) for the handful of features that need more than a flag flip — every hook is verified against an ECDSA P-256 signature before it's ever installed. - Import and export flag sets as .gmsflags files, including per-flag package overrides for multi-package apps. - Hook status dashboard — see at a glance which supported apps the Xposed module is actually attached to, and why one isn't. - Privacy-conscious analytics: opt-in, no PII collection — boolean/int/float flag values are logged to help shape recommendations, but string flags never are, since those can carry tokens or emails and stay on-device.

Disclaimer
GMS Flags changes low-level settings inside other apps. Most flags are harmless, but some can affect how an app behaves — every override is reversible, but you apply changes at your own discretion and risk.
