Screen sensitivity settings on iPhone XR

Hi. I have an iPhone XR and the screen seems to be EXTREMELY sensitive. If there’sa smudge or some dust/dirt on the screen it’ll interfere with what I’m doing by causing the screen to change from one app to another or press keys on my keyboard, etc. The screen picks up on whatever smudge or dust particle as it does someone’s finger. I am CONSTANTLY having to wipe down my screen and blow off any little

pieces of dust that might by on my screen. It becomes really annoying and makes it hard to do almost anything on my phone.

I found directions on how to change the screen sensitivity level but as far as what I learned you have to turn on the 3D Touch and Haptic Touch features. On my XR there’s no 3D option and the halt if touch only allows you to change how long you touch a picture for before it’s enlarged. There’s nothing that has to do with the screens sensitivity level.

If there’s a way to change/customize the screen’s sensitivity level on an iPhone XR I’d really appreciate someone letting me know how it’s done! Thank you!
