Use android:layout_centerInParent="true" like this:

<Button
    android:id="@+id/btnButton3"
    android:layout_width="75px"
    android:layout_height="50px"
    android:layout_marginTop="10dp"
    android:layout_centerInParent="true"
    android:layout_alignParentBottom="true"
    android:text="..."/>

You have to stop using px here. It might be the reason for your problem. Simply try it like this using dip, 

 <Button
        android:id="@+id/btnButton3"
        android:layout_width="75dip"
        android:layout_height="50dip"
        android:layout_centerHorizontal="true"
        android:text="..."/>

EDIT 1

        <Button
        android:id="@+id/btnButton3"
        android:layout_width="75dip"
        android:layout_height="25dip"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:text="..."/>

dip-density independent Pixels.

Here is the output,

Use layout_alignParentBottom="true" like this:

 <Button
        android:id="@+id/btnButton3"
        android:layout_width="75px"
        android:layout_height="50px"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        android:text="..."/>
