God Ray effect (light scattering) with Mali GPU

Hello everyone,
I'm implementing the God Ray effect for an Android game on Mali-400 based devices (here is Samsung I9100 and Samsung I9300).
I've followed this article
http://fabiensanglard.net/lightScattering/index.php
But the effect is not good (as you can see in the attached file).
It did work on Win32 and other Adreno and PowerVR based devices.
I think that there's problem with the texture's coordinate fetch from vertex shader to fragment shader, the interpolation computation may cause this issue.
I hope that you can give us some idea on this.
Thank you.

Many thanks Pete, it works like a charm.
We are trying to solve the fps issue as you said, it just 6fps.
Thanks,
