It's a known issue. If you go to the Android Developer's board, you'll
find more info on this.
Somehow, a touch-event being generated (not even handled) slows down
the phone quite a bit.
If your drawing/game thread is different from the main gui-thread
('OpenGL' for example), you can mitigate this slowness a bit by coding
something ugly your implementation of the onTouchEvent or
dispatchTouchEvent. You put a Thread.sleep(x) in where x is a small
number, usually around 20ms or so, upto 100ms.
In my opinion, this is a performance bug.
