Some of you probably know, but it was new to me. Playing Jetpack Joyride, i noticed that the screen would keep registering a touch after lifting my finger ever so slightly. Works best when using a thumb flat on the screen, because of the larger area, I guess. Must be the capacitive touchscreen doing its thing! Just never noticed before. You can test it with the lock screen slider, or basically anywhere else. It only seems to work when the finger is leaving the screen, not when it's approaching it. Anybody knows why?
