title: Draw over Other Apps Issue | switch is grayed out

  I followed this above post which I made work and bring up the intent prompt for my app to draw over others. Sadly I am finding that the <strong>switch is grayed out</strong>. After some googling </p>
  
  <p>I have seen that others have pointed towards screen filter services that are the culprit, except I do not have any of those installed. Also, I have seen that other apps (i.e. <code>Facebook Messenger</code>) are not grayed out and I can switch the <code>permission</code> on and off with no issues.</p>
  
  <p>Am I missing something in my code to cause they <code>permission</code> switch to be grayed out?</p>
  
  <p>EDIT:
  I found another post with nearly an identical issue using the same device running the same version of Android.
  <a href="https://stackoverflow.com/questions/35453759/android-screen-overlay-detected-message-if-user-is-trying-to-grant-a-permissio?rq=1">Android &quot;Screen Overlay Detected&quot; message if user is trying to grant a permission when a notification is showing</a></p>
  
  <p>tested in device <code>Moto</code> and <code>Nexus 6P</code></p>
  
  <p>More Edit:
  Also tested on <code>Samsung Galaxy S7 Edge</code> and <code>AVD</code> running <code>SDK 23</code> with the same result</p>
