title: Back Key button press not working on samsung phone
body: <p>I'm using a Samsung GT-5330 for installing my android app. I need to return to the first screen if a user presses the back button after confirmation of data. </p>
  
  <p>I'm using the following code: </p>
  
  <pre><code>  public override bool OnKeyDown(Android.Views.Keycode keyCode, Android.Views.KeyEvent e) {
  
  
            if (keyCode == Keycode.Back)
          {
  
              Intent i = new Intent(this, typeof(HotelSearchPage));
                StartActivity(i);
  
          }
          return base.OnKeyDown(keyCode, e);
  
  
           }
  </code></pre>
  
  <p>This works fine on my emulator, but is not working on my device. </p>
