---Overview---
From this priority desk case:
https://xamarin.desk.com/agent/case/108923

When an ActionSheet is opened and the user presses the back button in Windows Phone, it navigates to the previous page when the app is deployed in Windows Phone.

---Expected Behavior as follows---
1. Open App
2. Navigate to page with ActionSheet
3. Open ActionSheet on that page
4. Press Back button
5. ActionSheet disappears and user remains on ActionSheet page.

---Actual Behavior in WinPhone---
1. Open App
2. Navigate to page with ActionSheet
3. Open ActionSheet on that page
4. Press Back button
5. User is on page that was opened previously to the ActionSheet page.

I was able to reproduce the expected behavior using the Xamarin Android Player, and the Actual Behavior of the WinPhone bug in the Windows Phone emulator.

Fixed in next pre-release

Hi Jason

Unfortunately the X.F 1.3-pre3 release does not fix this issue. It is now worse. When I now press the back button on an open ActionSheet in WP8 then the application will crash:

   Object reference not set to an instance of an object.

You can reproducde the issue with the provided test project

Hi we can repo that issue on WP8.
Comment 9 Jason Smith [MSFT] 2014-12-15 09:29:30 UTC
Sorry about that, fixed again. Dont know how that got through really. Really wish we could run the UI test suite on WinPhone. Anyhow it has been fixed (again).
