I'm having the same issue - I even took off the screen protector to see if it made a difference (it didn't). The responsiveness of my screen is very erratic. Sometimes the lightest touch will work - at other times, I'm having to really press down. Non-responsiveness is particularly bad on the 'x' to close apps and the "end call" button for calls. But at times the pressure of my ear when I'm on a call is enough to activate various functions. I'm hanging in there so far - because I have absolutely no problems with keyboard lag - and that's important to me - but I can't seem to settle into a good pattern with the touch screen.
