Test case

On Android only, maybe only on LG phones, EntryCells in TableViews and ListViews lose focus while typing.

This behavior depends on the implementation of the default "LG Keyboard" on LG phones. Other soft keyboards might be affected too.

## Workaround on device

1. Install the "Google Keyboard" from the Google Play store. 
2. Set the "Google Keyboard" as the default input method instead of the "LG Keyboard".

## Workaround in the app

Add the following attribute to the MainActivity in the Android application project:
WindowSoftInputMode = Android.Views.SoftInput.AdjustPan

## Steps to reproduce

1. Run the Android project from the attached test case.
This test case is just a new "Visual C# -> Mobile Apps -> Blank App (Xamarin.Forms Portable)" with the code from [3].
> [3] http://androidapi.xamarin.com/?link=T%3aXamarin.Forms.EntryCell

2. Once the app launches on device, tap within the editable portion of the EntryCell.

3. Start typing "hello" using the on-screen keyboard.

## Result on LG Optimus L9 running Android 4.1.2, using the "LG Keyboard"

When the autocompletion bar appears, it immediately disappears and the text field loses focus. Further entries into the keyboard result in no changes to the text field.

## Expected result (using the "Google Keyboard")

The text autocompletion bar stays on screen, and the text field stays focused until the user explicitly sets focus outside of the text field.

The Android 4.0.3, 4.1.2, and 4.4 emulators all show this correct behavior.

## Results on iPhone, Windows Phone Emulator

By default neither of these systems shows an autocompletion menu. The text field stays focused as expected on both platforms. Dragging across the letters "hello" on Windows Phone *does* show an autocompletion menu. That autocompletion menu stays on screen as expected, and the text field does not lose focus.

I have checked this issue and observe that I am not getting this behavior with Xamarin.Forms: and X.Forms pre1.

I am able to reproduce this behavior with Xamarin.Forms: but I am not getting this issue does not exist with Xamarin.Forms:

Steps I followed:

1.  Create a Blank App( Xamrin.Forms Portable) application.
2.  Use the following test case
3.  Build and deploy application on LG nexus 5 ( Android 5.0)

Screencast  (Keyboard setting) : http://www.screencast.com/t/FlljrdX1A

This issue has been fixed. For now I am changing it's status to Resolved. Please check this with updated Xamarin.Forms package. 
If you face the same problem after updating the Xamarin.Forms package please reopen this issue.

I am facing this issue in Nexus 5X, Lenevo A600, One Plus 3 and other device as well.
Below is my data template in which i am binding entry fields dynamically 

<DataTemplate x:Key="Numeric">
            <StackLayout Padding="0">
              <StackLayout Spacing="0" Padding="10">
                <Grid ColumnSpacing="0" Padding="0" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
                    <RowDefinition Height="auto" />
                    <RowDefinition Height="auto" />
                    <ColumnDefinition Width="*" />
<controls:ExtendedLabel Text="{Binding .Question}" Style="{StaticResource ListItemInspectionLabelStyleWordwrap}" HorizontalOptions="Start" VerticalOptions="Start" Grid.Row="0" Grid.Column="0" />
                  <controls:XXXEntry x:Name="InputEntry" IsEnabled="{Binding .CanRespond}" FontSize="12" TextChanged="OnNumericTextChanged" HeightRequest="50" Keyboard="Numeric" Focused="OnNumericFocus" Unfocused="OnNumericUnFocus" HorizontalOptions="FillAndExpand" VerticalOptions="End" ClassId="{Binding .QuestionId}" Grid.Row="1"Grid.Column="0" />
              <BoxView Style="{StaticResource ListDividerStyle}" />

"XXXEntry" is my entry control if we more than 5 items(with scroll) then after entering/changing any value in 3rd entry field then on each key press unFocus and Focus will fire more than 2-2 times.

Please do needful.
