title: iOS Microphone Option Not in App Settings Even Though Permission was Given
body: <p>I'm having a weird issue with asking for permission to the microphone on iOS 10. I put the proper plist property (Privacy - Microphone Usage Description) and enabling it through code. On my phone, the microphone works/enabled and I see it in my phone's settings for the app. However, on a friend's phone, the microphone asks for permission but then the microphone option doesn't show up in the app's settings. Am I missing something here even though I set the permissions correctly? Why would my phone show the option in the settings but not my friend's phone? I have an iPhone SE and my friend has an iPhone 6s.</p>
  
  <p>plist property:</p>
  
  <pre><code>&lt;key&gt;NSMicrophoneUsageDescription&lt;/key&gt;
  &lt;string&gt;Used to capture microphone input&lt;/string&gt;
  </code></pre>
  
  <p>code asking for permission:</p>
  
  <pre><code>if ([AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio] == AVAuthorizationStatusAuthorized) {
      [self configureMicrophone];
  }
  else {
      UIAlertController *deniedAlert = [UIAlertController alertControllerWithTitle:@"Use your microphone?"
                                                                           message:@"The FOO APP requires access to your microphone to work!"
                                                                    preferredStyle:UIAlertControllerStyleAlert];
      UIAlertAction *action = [UIAlertAction actionWithTitle:@"Go to Settings" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action){
          [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
      }];
      [deniedAlert addAction:action];
      [self presentViewController:deniedAlert animated:YES completion:nil];
  }
  </code></pre>
  
  <p>Thanks!</p>
