  2. Go to and tap on Accessibility
  3. Look for and select the Audio/Visual option. 
  4. Tap on the Phone Noise Cancellation toggle switch. If it is not green, that means it is disabled already. 

After turning it off, test your microphone’s functionality to determine if the issue has been resolved.
