The article mis-interpret the data. It actually measures the full UI latency, which includes touch input, event system, and UI graphics system. It is somewhat well know that Android event and graphics systems have higher latency. At least, I took it for granted for 5 years. The touchscreen is a hardware component, its latency mostly depends on hardware choice. Nintendo 3DS and PS Vita have much lower latency, because the software stack is highly optimized for games (which obviously wants low latency).
