Tired of slow Android Auto feature rollouts? This new tool lets rooted users skip the wait

Google is notoriously slow with how it rolls out features to Android Auto, often hiding fully functional interface changes behind server-side flags, extremely extended testing phases, and very selective drip-rollouts. While we’ve recently seen community projects like Android Auto Maker expand what you can do on your car’s screen, tinkering with the core Android Auto platform has historically required messy system-level patching. Now, an open-source LSPosed module called AA Experiments lets rooted users take control, giving them an interface to easily inspect and selectively override Android Auto’s hidden experimental flags.

AA Experiments by developer HighwindBR pairs an Android manager app with an LSPosed module that hooks directly into Android Auto without modifying or repacking the APK. The app scans the installed Android Auto build on your phone, does its magic in the background to let users toggle hidden features on and off.

The app was born when the developer got tired of waiting for Android Auto’s light theme to fully roll out, and so took matters into their own hands.

The scope of what can be toggled stretches well beyond day and night themes, however. The developer has documented over 100 active flag overrides covering various Android Auto interface elements. These include Gemini Assistant personalization, wallpaper-derived theming, quick settings panels, edge-to-edge maps, multi-card media dashboards, toggles for immersive full-screen apps, and more.

One of the main hurdles with such flag-based experimentation is app safety and version compatibility. AA Experiments addresses this by binding overrides to the exact build of your installed Android Auto package. If Google pushes an app update and some flag signatures change, the module suspends conflicting mappings rather than blindly forcing them and crashing your head unit. There is also a one-tap restore option to revert to default behavior.

This vibe-coded project is also free, open-source, and claims to operate completely offline with no tracking or telemetry.

The big caveat with AA Experiments, though, is the fact that you need root access as well as working LSPosed on it, so not everyone will be able to enjoy these experimental Android Auto features. It joins other recent community utilities, like the UnknownAuto sideloading tool, in granting power users greater autonomy over their car’s infotainment setup.
