I have seen some folks comment that their screen icons do not respond quickly enough when touched or that once in a while there is a noticeable delay.
This raises the question, is the original screen GLASS? I ask because glass is fairly difficult to scratch.
I say this because everyone I know, including myself, has a scratch-resistant plastic shield over the original phones screen and it could be that this plastic shield sometimes makes it take a teeny-weenie (this is a technical term) bit longer for the icon to react to your touch.
Therefore if the screen is glass, I want to remove the scratch-resistant plastic cover and see if icons react quicker to my touch without the plastic cover over the screen..
