Example project reproducing the issue. One image is right be navigating back. The second image is after you navigate back, and you see the resize issue.
I've provided screenshots of the bug in the attached zip file as well as an the example project used to reproduce the issue.
I am having resize issues after navigating back to a page when the keyboard is up.
Been trying to tackle this bug on my own for a couple of days now. It seems to be something internally with forms as I cannot reproduce it in a native android app even with the same way FormsAppCompatActivity uses the FragmentManager. Currently, this is a bit critical.
Steps to reproduce:
1) Open the attached zip file.
2) Open AndroidBlankSpaceForms.sln.
3) Build and run the AndroidBlankSpaceForms.Droid project on a device (preferably a lower-end device).
4) Once the app loads, tap on "Next Page".
5) Next, select one of the entry controls on the page you navigated to.
6) While the keyboard is up, press the back arrow on the action bar.
7) When you are back to the first page, you should see the first page not properly resized.
If you are having issues reproducing this bug, increase the 'number' variable in App.cs to something like a 1000.
This is fixed in 2.3.1. Please update packages of your test project.

I thought the proj was in 3.1. I'm sorry.
