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 (!).

Wow.

> I often have to make repeated presses on my iphone until it registers.

This makes me really curious.

And you seem to have a problem with all your Apple devices. That’s why I wondered whether you’re experiencing that only with Apple or whether it happens with Android devices as well. Perhaps you could borrow a friend’s, or try using a demo phone at a store etc.

Also have other people use your problematic devices and see if they experience a problem.

I’d love to dig into this further with you (because, curiosity), but alas we live in different universes.

Wishing you a speedy recovery from your cold.
