Can you calibrate the touch screen on an iPhone?

Over the years, I have dropped my phone a couple times and now the screen is cracked (I have a nice screen protector). Since then, the ability to control the cursor has diminished. I used to be able to point to a place on the screen when I moved the cursor and now it can be words or even sentences off.

Am I stuck with this until I replace the screen or is there a way to calibrate the screen with your finger?
