Description Michiel van Vlaardingen 2015-03-02 17:49:02 UTC
Given a ContentPage containing a webview,  if an input field on the webpage is focussed and keyboard is shown, it is no longer possible to scroll the page up or down. Not even after the keyboard is hidden again.   This is a showstopper bug for us as it makes the oauth linkedin page unusable.

Issues is Android only  and did not exist in version 1.3.1. (but does exist in 1.3.4 as well)

Tested on Android 4.1.2 (Samsung S2)

I have checked this issue with help of sample application attached in Bug description and able to reproduce it with 'samsung glaxy s3'. I run app on samsung glaxy s3 version 4.1.1, app launches on the device and I am able to scroll up and down the webpage. But if I click in textbox then Webpage is no longer possible to scroll up or down, even after hiding the keyboard.

Note: It is working fine on htc one version 4.4.2 and emulator, http://www.screencast.com/t/YKHQPtsZM1

I have checked this issue with Xamarin Forms version and both.

Should be fixed in 1.3.5 hotfix 1

Customer for the case I noted in comment 3 reports that the fix in Xamarin.Forms appears to be working based on their initial tests.
