When we navigate back from native page in Android, it always navigates back to empty page
We have to press the back button twice to get back to original page that started the native page (using page renderer)
Test case: https://github.com/xamarin/xamarin-forms-samples/tree/master/Forms2Native
Steps to reproduce
1. Run the Forms2Native App
2. Click “Click to see an Intent work” in the main screen, and a new “page” should start
3. Click Back, either the UI button on the screen or the hard/dedicated button on the device.
4. When clicked once, you arrive at an empty page
5. Clicked again and you arrive where you were supposed to arrive at after the initial Back click.
I have checked this issue and with the help of steps mentioned in bug description I am able to reproduce this issue.
I have downloaded the "Forms2Native" sample from following url.
When I run the sample app and press the back button I observed that it navigates back to the entry page and when again I press the back button then it navigates to original page.
I have checked the same with device and getting same behavior.

This is an issue with how the sample is implemented, not a bug in Forms.
It seems like it's not a sample bug. It's a feature!
Sample demonstrates two different types of navigation:
1) "Click to see a native page" shows how to use Navigation.PushAsync and it opens the Second page of the app
2) "Click to see a na intent work" shows how to perform navigation with messaging and it opens a Third page of the application.
