When you edit a value of a certain item of the DataGrid and keyboard is displayed, while the focus is still in the input and the row is scrolled away, the keyboard will stay open on Android.

In addition, if you return back to the edited cell, the row will display as if it were on focus, the cell shows the editor underline, the keyboard is still open, but there will be no focus.  You will be required to click on the cell to get focus again.

Lastly, only on Android 5.1, if the edited value is a number, when you scroll the cell out of view, the keyboard changes from the numerical to alphanumerical (default).

 If you open a datagrid's filter pop-up, navigate away from the page, then go back to the page, the filter pop-up will still be open.

If you attempt to close it, by way of the "X", the app will crash. In debug mode, a null reference error will occur. If navigating away from the grid with the filter closed, no crash will happen.

You can reproduce this by changing input language to any region that uses a comma decimal separator (e.g. Duetsch). The comma is ignored, ultimately corrupting the data

If you define a PropertyGroupDescriptor in XAML or in page constructor and the PropertyName is set to a nested property, the grouping is not applied.

Grouping by a nested property works correctly when called from the Filtering UI or on a button click action.

Refer to the attached reproducible.

1. Run app and apply a filter: "Contains 0"

2. Notice #40 is in the correct location, between #30 and #50

3. Press the button on the bottom of the page to go BlankPage and then navigate back.

4. Observe #40 is now at the end of the rows even though the filter is clearly applied.

Look in MainPageViewModel.cs lines 42 to 49. When the navigation back occurs, this code is executed.  I can reproduce the problem with both Replace and Add+Remove operations.

public override void OnNavigatedTo(INavigationParameters parameters)
{
    base.OnNavigatedTo(parameters);

    if (!parameters.ContainsKey("from"))
    {
        var items = new ObservableCollection<MyModel>();
        for (var i = 1; i <= 100; i++)
            items.Add(new MyModel { Number = i.ToString() });
        Items = items;
    }
    else
    {
        var item = Items[39];

        // Bug Test #1 - using ObservableCollection Reset
        Items[39] = item;

        // Bug Test #2 - using ObservableCollection Remove & Add
        //Items.RemoveAt(39);
        //Items.Insert(39, item);
    }
}

Column names in column selector are not visible in Android the first time the column selector is shown. This happens only in the case UserFilterMode is disabled.

After scrolling down enough times where all of the data is loaded, if I try to scroll a bit more, things go a bit crazy.  A loading icon flickers on and off over the grid; the data in the grid flickers away and then back; and the entire UI essentially gets stuck in this situation.

Flicker can be observed when datagrid is manipulated/updated, or entering in edit mode. One example is tapping on a column header - when there is a column with a HeadetTemplate, the column header flickers. Other example is to double-tap a cell to go in edit mode. Also the behavior can be reproduced when DataGrid TemplateColumn is used.
