1. Create a project which displays info for every touchscreen touch
2. Deploy it to device
3. Start tapping screen with one finger at the same place
4. Notice that, even though there were no simultaneous physical touches on the screen, device registers tap counts on two separate touches.

Why is this not going to be fixed?
There is no way to find out whether subsequent touches came from the same finger or not, as OS gives unique finger ID for each touch event. Unlike on Android, where repeatedly hitting with one finger gives same finger ID every time. Since destruction of touch slot is delayed for 150 milliseconds, hitting twice faster than that will cause second event registered to the second slot.
