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

[KrithikaIrulappan18]

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.
