title: Xamarin: Detect device rotation when orientation is locked? For iOS and/or Android?
body: <p>I am working on a Xamarin.Forms app that plays videos similar to a YouTube type app. I want the video to go full screen when the device rotates (like youtube does) but I also want the orientation to be locked in to portrait. Every post or tutorial I've found points to using  custom renders for detecting orientation change to determine when the device rotates, but when orientation is locked those events do not fire.</p>
  
  <p><strong>Is there a way to detect device rotation without depending on orientation changing?</strong></p>
