title: Check Fire OS version programmatically
body: <p>I'd like to check programmatically the Fire OS version of my running device. <strong>Not the Android version</strong>. </p>
  
  <p>The reason I want that version is because there is one capability which is not shown on old Fire OS versions and I'd like to include it on my app. </p>
  
  <p>Note: sometimes the devices are not updating the OS immediately.</p>
