This appears true. I have a Nexus S and I have seen some times that the touchscreen freezes after I finish the call. It usually happens on a hot day and if there is sweat on the screen. When I press the power button and unlock again, things are back to normal. Have checked with some of my friends who use iPhone and they do not seem to have experienced such issues.
