Dead zones on the corner of touchscreen?

My iPhone 11 seems to have developed a couple dead zones in the upper (high use) corners. It can’t sense my finger. I’ve tried warming up my hand, pressing longer, using my thumb (wider than my pointer finger) but it appears to be getting worse. Has anyone else experienced this and is there a solution—like resizing everything so that I don’t have to use the entire screen? I have a tempered glass protector on my screen but have used this for years, across generations of iPhones so I don’t think that’s impeding anything. I also haven’t dropped my phone. Thank you
