A former intern for Google's Android team has provided explanations for why Android experiences more touch interface lag than competing mobile operating systems from Apple, Microsoft and Research in Motion.
Undergraduate software engineering student Andrew Munn posted his observations on Google+, as noted by Cult of Mac. He did disclaim, however, that he will be starting an internship with Microsoft's Windows Phone team in January, adding that any opinions from the report were his alone.
According to Munn, Android has a difficult time dealing with the touch interface because it handles rendering "on the main thread with normal priority," as opposed to iOS, which treats UI rendering with real-time priority. He cites examples of website loading and the Movies app on Android where the operating system will continue to load while registering touch input.
