title: OnLeScan continue firing after bluetooth is switched off
body: <p>It is teoretical question.</p>
  
  <p>One of the customer devices(android 8 htc 10 ) continue firing <code>OnLeScan</code> callback after he dissables bluetooth module in settings. He could reproduse it only on  the <strong>htc 10</strong> device.</p>
  
  <p>Steps</p>
  
  <ol>
  <li>start app with bluetooth on</li>
  <li>app discovers beacons</li>
  <li>swith off bluetooth</li>
  <li>app continue firing <code>OnLeScan</code></li>
  </ol>
  
  <p>I understand that it is not possible(i can't reproduce it on other devices), but I get this situation.</p>
  
  <p>Now I'm planning disable ble scanning when Bluetooth state is changed, so I think this will help me to fix this problem...</p>
  
  <p>But still I don't understand why it is works like this. Do you have any ideas what can be wrong?</p>
