How to take the picture taken from the camera, not the camera preview

Good afternoon guys, I'm using this multiplatform camera project of the xamarin.

In the Android part, I'm not getting maximum in the photo, I'm using this function:

System.Collections.Generic.IList<Android.Hardware.Camera.Size> sizes = parameters.SupportedPictureSizes;

    // Iterate through all available resolutions and choose one.
    // The chosen resolution will be stored in mSize.

    foreach (var size in sizes)
    {
        Console.WriteLine("Available resolution: " + size.Width + " " + size.Height);
        mSize = size;
        if (1920 <= size.Width & size.Height <= 1944)
        {
            Console.WriteLine("Chosen resolution: " + mSize.Width + " " + mSize.Height);

            parameters.SetPictureSize(mSize.Width, mSize.Height);
            orgPreviewWidth = mSize.Width;
            orgPreviewHeight = mSize.Height;

        }

It is taking the resolution I want, but I noticed that when saving the photo, saves with the size of the preview of the macera, which varies from mobile to mobile, as it generates a Bitmap of Preview(TextureView)

Here, I'll move the size of the preview, if I by the resolution of the photo I want, the screen is stretched all the way

textureView.LayoutParameters = new FrameLayout.LayoutParams(widht, height);

To save the photo:

var image = textureView.Bitmap;
var absolutePath = Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDcim).AbsolutePath;
var folderPath = absolutePath + "/" + "Album";
var filePath = System.IO.Path.Combine(folderPath, string.Format(MainPage.data + contador + "_frente.jpg", Guid.NewGuid()));

var fileStream = new FileStream(filePath, FileMode.Create);
                        await image.CompressAsync(Bitmap.CompressFormat.Jpeg, 100, fileStream);


fileStream.Close();
image.Recycle();

var intent = new Android.Content.Intent(Android.Content.Intent.ActionMediaScannerScanFile);
                        var file = new Java.IO.File(filePath);
                        var uri = Android.Net.Uri.FromFile(file);
                        intent.SetData(uri);
                        Forms.Context.SendBroadcast(intent);

Does anyone know if there is a solution for this?
