iPhone 12: Fix No Sound During Calls with These Simple Steps

Troubleshooting Call Audio Issues on iPhone 12

• 💡 Check call volume during an active call by pressing the side button to ensure it's turned up to the maximum.
• ⚠️ Ensure the volume slider shown is for call volume, not media volume, and adjust accordingly.

Ruling Out Bluetooth Interference

• 🔌 Disable Bluetooth either through the quick settings icon or by navigating to Settings > Bluetooth.
• 🎧 This step helps eliminate issues caused by connected AirPods, other headphones, or external speakers automatically routing call audio.

Testing Call Functionality

• 📞 Test call audio using the native Phone app or other calling applications like WhatsApp or Discord.
• ✅ Using multiple apps helps determine if the issue is specific to the Phone app or a more general audio problem.

Restarting and Updating Your iPhone

• 🔄 To restart your iPhone 12, press and hold the power button and the volume up button simultaneously until the 'slide to power off' appears, then slide. To complete the restart, hold only the power button until the Apple logo is visible.
• ⚙️ After restarting, check for iOS software updates by going to Settings > General > Software Update.
• 🚀 If an update is available (e.g., from iOS 26 to 26.1 or higher), install it, as updates often contain fixes for audio problems.
