I use handcent SMS as my default messaging app. I noticed that when I receive an SMS my pop up notification turns my screen on and at the same time my Samsung unlock sound goes off.
If I reply or close out the pop up notification then I automatically hear the lock sound of the Samsung phone (the ripple sound)
