Image in scrollview doesn't display properly

Question

I having a problem to display the image nicely at different devices. Example of S3 Device, they displayed the way I wanted:

However is S6 Device, the image display is too small especially for portrait images.

Anyone got idea how to solve this issues because I tried to use weight , match parent etc doesn't really work on it. p.s. when i put my imageview above scrollview , sometime work quite perfectly.

Below is my current XML

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    >
    <include
        layout="@layout/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />


    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <LinearLayout
            android:padding="10dp"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_weight="1">

                <ImageView
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:id="@+id/ivEventInfoPoster"

Try this with your ImageView

<ImageView
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:id="@+id/ivEventInfoPoster"
  android:src="@drawable/carfreeday"
  android:scaleType="fitStart"
  android:adjustViewBounds="true"                 
  android:contentDescription="@string/common_img_desc"
/>
