[Android] Line breaks not occurring when pressing Enter in Entry configured as multiline, even with ImeOptions set to None.

Description

In .NET MAUI, pressing the "Enter" key in the Entry field does not produce a line break by default. Although platform-specific workarounds have been implemented to enable multiline behavior, this functionality fails on certain Samsung Android devices, including the Samsung F14, Samsung Galaxy S8+ Tablet, Samsung Galaxy Active Tab 3, and Samsung Galaxy Fold 6. It is suspected that, on these devices, the "Enter" key triggers the "Done" or "Send" action instead of inserting a line break. Even after setting ImeOptions to None, the expected line break functionality does not work when the "Enter" key is pressed.

Steps to Reproduce

1.Create a .NET MAUI application with an Entry field intended to support multiline input.

var entry = new Entry
           {
               Placeholder = "Enter your text here...",
               HeightRequest = 150, // Height to accommodate multiple lines
               HorizontalOptions = LayoutOptions.FillAndExpand,
               VerticalOptions = LayoutOptions.StartAndExpand
           };

2.Apply platform-specific configurations to enable multiline behavior, including setting ImeOptions to None for Android.

entry.HandlerChanged += (sender, args) =>
           {
               if (entry.Handler != null)
               {
#if ANDROID
                   if (entry.Handler.PlatformView is EditText editText)
                   {
                        editText.SetSingleLine(false); // Allow multiline behavior
                        editText.InputType = Android.Text.InputTypes.ClassText | Android.Text.InputTypes.TextFlagMultiLine;
                        editText.ImeOptions = Android.Views.InputMethods.ImeAction.None;
                        editText.SetHorizontallyScrolling(false); // Wrap text within bounds
                        editText.SetPadding(10, 10, 10, 10); // Add some padding for better appearance
                   }
#endif
               }
           };
           // Add the entry to the layout
           Content = new StackLayout
           {
               Padding = new Thickness(20),
               Children = { entry }
           };

3.Deploy the application to the following Samsung Android devices:

Samsung F14
Samsung Galaxy S8+ Tablet
Samsung Galaxy Active Tab 3
Samsung Galaxy Fold 6

4.Focus on the Entry field and press the "Enter" key on the keyboard. 5.Observe whether a line break occurs in the Entry field.
