Bluetooth Volume Manager can react to Bluetooth devices connecting or disconnecting. It allows Android to remember the volume levels of different Bluetooth devices.
Available features: • Music, call, ringtone and notification volume adjustment. • Sending out 'Play' or 'Next' media commands. • Opening a specific app. • Keeping the screen awake. • Preventing the volume from being changed. • Restoring previous volume levels after disconnect.
This app can't "boost" your volume or change the volume if you can't change it through your device's volume buttons manually.
Permissions explained: • 'Internet' for bug reports. • 'Bluetooth' to work with Bluetooth devices. • 'Modify audio settings' to change volume. • 'Boot completed' to restore volume levels after reboots. • 'WAKE_LOCK' to fix a bug on Samsung devices and to keep the screen awake if necessary. • 'SYSTEM_ALERT_WINDOW' to launch apps when a Bluetooth device connects (only on Android 10).
