title: How to detect/identify if device Lock Screen setting is set to None?
body: <p>I need to check before enabling my application if the device has no security defined on setting.</p>
  
  <p>Can't have set: Pattern, PIN, Password and even Swipe.</p>
  
  <p>Does anyone know a way to check if the lock screen setting is not enabled?</p>
  
  <p>Alternately, can we check which of the above lock screen settings is enabled?</p>
  
  <p>Thanks!</p>
