title: Vibration not ocurring on React-Native Android Device when unplugged
body: <pre><code>import { Vibration } from 'react-native';
  
  const handleThrottledShake = () =&gt; {
    Vibration.vibrate(500);
    console.log('ran vibration');
  }
  </code></pre>
  
  <p>I'm currently developing a react-native app and running into some trouble. When connecting my phone via a usb cable, vibration works. However, when I unplug it, everything else works, including <code>console.log('ran vibration');</code> but no vibration actually occurs. <a href="https://facebook.github.io/react-native/docs/vibration" rel="nofollow noreferrer">The docs</a> say  say that vibration doesn't work on an emulator, but I'm using a physical device (OnePlus6), so I don't think that's the issue.</p>
  
  <p>Does anybody have any ideas on what could be the problem?</p>
