title: Page is greyed out when search button is pressed
body: <p>I'm working on a app in Xamarin forms and I'm having a problem..</p>
  
  <p>I've got a search page with a search bar and when the search button is pressed it slightly grey out the page, this only happens on the android version. </p>

  <p>The problem is that if I don't delete the search text manually the whole app is slightly greyed out, until I go back to the search page and click the search bar, then the grey tint disappears.</p>
  
  <p>Have someone else experienced this?</p>
  
  <p>As mentioned, this only happens on android, not iOS.</p>
  
  <p>I'm using Xamarin forms 4.3 if that helps.</p>
