getPressure always returning 1.0

Question

Does anyone have any idea why getPressure() returns always 1.0?

Here is my code:

@Override
    public boolean onTouchEvent(MotionEvent event) {
        super.onTouchEvent(event);

        System.out.println(event.getPressure());

        return true;

    }

The typical touchscreen / input device has no way to measure pressure. You either don't press and get no touch event or you press and get a touch event with value 1.
