ImageSource.FromUri not display on iPhone 6+

I have a list of items, each item has an image like this:

var image = new Image
            {
                WidthRequest = 44,
                HeightRequest = 44,
            };
            image.SetBinding(Image.SourceProperty, new Binding("ImageUrl"));

Almost all images are displayed fine in iPhone 5S and 6+ (simulator/real device). However, there is an image which is not displayed on iPhone 6+ (simulator/read device). I tried not setting Width and Height Request but it didn't solve the problem.

This is the info of the exceptional image:

Size: 9KB (12KB on disk)
Dimension: 608 x 369
Color Space: RGB
Color Profile: Generic RGB Profile
Alpha Channel: Yes

Thank you for helping!
