iPhone 12 Pro max. Ghost touch.

Hello I have an iPhone 12 pro max from Verizon. I have now had 12 separate iPhone 12 Pro Max is from Verizon. Each time I receive one after a few months it starts touching random places on the screen and nothing I do fixes the issue. My current phone has the newest update that it says I can get lunch is 15.5. I have reset the settings and wipe the entire phone. I have done this with the last 12. I do not have money To take the phone to Apple. Every where I look I can’t find anyone with this issue.
