Who knows? Maybe maybe not? Like one doctor said to me - neuropathy is weird.
Edit - I decided to look it up and stop wandering what if and it turns out what I was thinking about the sensory issues was indeed correct!
“ Neuropathy causes trouble with touch screens because it reduces tactile sensitivity, fine motor control, and finger pressure awareness.
Why Touch Screens FailReduced sensation: Numbness or a "pins and needles" feeling means your fingers cannot accurately sense the glass surface or register a firm press.
Loss of fine motor skills: Nerve damage makes precise tapping, swiping, and holding difficult.
Altered fingerprints: Certain medical treatments or conditions change or smooth out fingerprints, which can block both tactile response and biometric scanners”

@megidigo It is not a pressure thing well not with my wife, most modern touch-sensitive devices don't work by pressure. They use capacitance your finger changes the electrical field/capacitance at the screen, which the electronics detect. Older resistive touchscreens did work by pressure, but modern screens generally use projected capacitive touchscreens. I see my wife prodding away at a screen, she is hitting the correct area, time and again, with much force or gently and it does not work, slow or fast. When I first worked on using touch screens many years ago many were pressure sensitive but the newer capacitance devices were a game changer and are generally adopted now since around 2000 to 2010, but the idea has been around since the 1960's if I remember. A friend worked on them in the 1980, but I lost touch with him. So I think it is these newer devices, that are the issue? Thanks Jon

Just one more reason to dislike neuropathy. 😊
