A simple yet powerful Android utility to help you manage your device's audio input source. Perfect for gamers, streamers, and anyone who wants more control over whether their phone uses the built-in mic or a connected Bluetooth headset.
- 🎧 Device Discovery: Automatically scans and lists all available audio inputs, including the internal microphone, wired headsets, and Bluetooth devices.
- ✅ Set Preference: Choose an input device from the list. The app will then run a background service to strongly suggest to the Android system that your chosen device should be used.
- 🔄 Revert to Default: A one-tap button to stop the service and instantly return all audio control to the standard Android OS behavior.
- ✨ Modern UI: Built with a clean splash screen and modern Material Design components for a great user experience.
This app uses official Android APIs to influence, but not force, the microphone selection.
When you select a Bluetooth device and tap "Set," the app starts a background service. This service constantly tells the Android AudioManager: "Hey, a Bluetooth audio connection is active and important!". Most apps (like games or voice recorders) will listen to this system-level hint and automatically use your Bluetooth mic.
Important Limitation: This app cannot force another app to use a specific microphone. Android's security model prevents one app from hijacking another's audio stream. Our method works for the vast majority of apps, but some may be hard-coded to ignore system suggestions.
