I just an optical bought of 1600 DPI resolution. The first one which I bought had right click problem and I thought that it was vibrating. I got it changed and right click problem was solved but the pointer is still vibrating on the screen. I have no phones around me that might do it. Maybe it's just that optical mouse is new to me? What might be the problem?
I've seen that happening a few times... Not sure what it is, maybe the mouse it on an uneven surface or something?
