    Hi walid fikri,

    Thank you for reaching out to Microsoft Q & A forum.   

    follow these steps to resolve the issue: 

    1.Run Application in Debug Mode: Start the application in Debug mode and monitor the Visual Studio Output window for any runtime errors or exceptions that may provide clues to the blank display issue. 

    2.Check Xamarin.Forms or .NET MAUI Versions: Ensure that you are using the latest stable versions of Xamarin.Forms or .NET MAUI and all related dependencies to prevent potential compatibility problems. 

    3.Validate Xamarin Essentials Configuration: Verify that Xamarin Essentials is correctly referenced and initialized in your project to utilize platform-specific features such as the PhoneDialer. 

    4.Review XAML and Code Integration: Double-check the integration between your XAML layout (MainPage.xaml) and its corresponding code-behind file (MainPage.xaml.cs) to ensure that all UI elements (Label, Entry, Button) are correctly defined and referenced. 

    5.Restart Emulator or Physical Device: Attempt to resolve display issues by restarting the emulator or physical device where the application is being tested. 

    6.Perform Clean Rebuild: Execute a thorough clean and rebuild of the entire solution to ensure that all recent changes, including updates to XAML and code, are correctly applied. 

    7.Verify Android Manifest Settings: Confirm that your AndroidManifest.xml file includes necessary permissions and <intent> queries, particularly those related to dialing functionality (android.intent.action.DIAL). 

     Please feel free to contact us if you have any additional questions.
