POCO M8 Pro 5G: Fix No Sound During Calls Step-by-Step

Troubleshooting Call Volume

• 💡 Max out the call volume using the side buttons while on an active call, as this setting is separate from media volume and not accessible in general sound settings.
• ⚠️ Ensure you are on an active call to adjust the specific call volume slider.

Ruling Out External Interference

• 🔌 Disable Bluetooth to ensure no connected headphones, car systems, or other devices are interfering with call audio.
• 🧼 Clean the earpiece gently with a soft brush to remove any dust or debris that might be obstructing the sound.

Software and System Checks

• 📲 Test with another calling app like WhatsApp to determine if the issue is with the default phone app or the system's call handling.
• 🔄 Reboot the phone by holding the power and volume up buttons and selecting 'Reboot' to refresh the system and resolve temporary glitches.
• 🚀 Check for software updates by navigating to Settings → About phone → HyperOS, as an outdated system can cause audio issues.
