As seen here my app gets shrinked on Samsung Galaxy Tab with Android 3.0
It is also shrinked in emulator, but at graphical layout it looks ok. main.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<WebView android:id="@+id/web_engine"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
It is OK on phone screens.
