With the phone sitting *idle*, Dalvik GCs every 3.5sec on average. A GC usually takes ~260ms. That means that a whole 7.4% of the time it is garbage collecting (albeit for only a quarter of a second each time). *7.4% of the time* the UI is completely unresponsive (and this percentage increases once your UI starts allocating its own objects during user interaction). This results in all sorts of unpleasantness that goes deeper than overall jerkiness of the UI:
