1. Press and hold a finger in the blue area (do not move this finger) 2. Tap a second finger somewhere else in the same blue area (again, do not move your finger only tap) 3. Observe the orange bar. It should become green when both finger are touching the screen. Response time should be near instantaneous. It is not. Additionally, about 1 out of 3 touches results in an inconsistent state in which the bar remains green after both fingers are removed. I'd remove the "straight down" part altogether.
