Call Volume Booster helps you optimize your phone's call sound so you never miss a word during conversations.
The app uses safe Android system settings to maximize and fine-tune your call volume for better clarity.
It does not record, capture, or share any audio. All adjustments are done only within your device using
official Android features.

✨ Key Features:
• Boost call sound clarity up to your device’s maximum safe level
• Simple ON/OFF control to enable or disable the booster anytime
• Persistent notification for transparency while the service is active
• 100% safe – no audio recording or microphone access required
• Optimized for Android 13 and Android 14+ devices
• Lightweight and battery-friendly

🔒 Privacy & Safety:
This app never records or transmits your calls. It only adjusts system audio settings such as call stream volume
and equalizer, using Android’s official APIs. Your privacy is fully protected.

⚙️ How it Works:
When enabled, the booster ensures your call volume is set to the maximum safe level and applies equalizer
enhancements to improve voice clarity. The service runs only while you choose to keep it enabled.
You can turn it OFF anytime from the app or directly from the notification.

📱 Why Use Call Volume Booster?
Sometimes your phone’s default maximum call volume feels too low, especially in noisy environments.
This app helps by making voices clearer and louder within the limits allowed by your device hardware.
It does not bypass safety limits and remains fully compliant with Google Play policies.
