I launch a page on UWP thanks to PageRenderer, this page allows take picture and I want go back when user take a pciture.

My problem is when I go back with hardware button I have no problem but with function goback doesn't work.

This is my code : 

```
 var frame = Window.Current.Content as Frame;
                if (frame != null && frame.CanGoBack)
                {
                    frame.GoBack();
                }

```

CanGoBack return false.

So you have **some idea**

Thanks
