Quick answers

Good to know.

Can this identify a touchscreen dead zone?+

It can help reveal an area that consistently misses or drops touches, but it cannot distinguish a hardware fault from an operating-system or browser issue.

Why does the page show only one touch point?+

Your device, browser or accessibility settings may limit multi-touch input. Try another browser and confirm multi-touch support in the device specifications.
