Android checkbox default behaviour is different on phones and tablets

I am using a standard android checkbox in my application like this.

<CheckBox
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="top"
    android:textColor="@color/white"
    android:textSize="12sp" />

The checkbox's default behavior of checked is displayed in phones but it remains unchecked in tablets. Am I missing something here ?
