Troubleshooting Call Audio Issues on OnePlus 15R

• 🔊 Check call volume specifically by tapping the volume bar during a call and accessing the three-dots menu to adjust the phone icon slider.
• 🎧 Disable Bluetooth to ensure audio isn't being rerouted to a connected device.
• 🧼 Clean the earpiece gently with a soft brush or microfiber cloth, avoiding metallic tools, to clear any potential blockages.

Advanced Settings and Software Checks

• 📱 Test audio in other apps like WhatsApp or Messenger to differentiate between system-wide and app-specific issues.
• ⚙️ Navigate to Sound & Vibration settings and explore sound effect options, including adjusting the sound mode and disabling 'Holo Audio' temporarily.
• 🔄 Restart your OnePlus 15R by pressing the power and volume up buttons simultaneously and swiping to reboot.

Resetting Network and Bluetooth Settings

• ⚠️ As a last resort, reset network and Bluetooth settings to resolve potential software routing or connectivity conflicts.
• ⚠️ Be aware that this action will also disconnect from Wi-Fi networks and Bluetooth devices.
• ✅ After the reset, perform a final check to see if the call audio has been restored.
