We’re going off track, but I’m curious as to whether you experience this problem only on Apple devices, and not – for example – Android devices?
(btw, it’s an honor to be able to reply to you; hope you’re doing well :) )
I have a cold, but all in all I'm doing very well. Thanks for asking!
My portable electronics devices are Apple. But there are other touchscreen products I have, like the thermostat and the one in the car. Sometimes they work, sometimes not.
Of course, buttons wear out. The membrane cracks or the conductive material rubs off. It happens with my computer keyboard. Fortunately, the keyboards are cheap and I replace them regularly. For my car with the touch screen, the service manager at the dealership told me that if the touch screen went out, the car would be totaled (!).
IME, Apple is (as usual) the worst. A Samsung I could even use with work gloves on. A Pixel not quite as well, but it still works great with gloves off as did LG and Sony and whatever else I've used over the years.
