Did a recalibrate on my screen. The area got smaller. Is my issue possibly dirt or bad calibration on my end or is the digitalizer dying?

so I took some of your guys advice… I think I may just have to remove my screen protector and recalibrate one more time and I think the issue may go away. I also heard you can take a toothbrush if its a dirt issue between the screen. I am mainly posting to see if this amount of success after recalibration means it might be not a dying digitalizer after all 😭
