This happens to everyone's fingers to some extent because the fingertips dry out as you age. It's a huge source of frustration for elderly folks since it adds to the confusion around using touch interfaces. My family members have had some success moistening their fingers with a wet paper towel periodically as they use their devices, though of course that is impractical on the go.

Do iphones not have "increase touch sensitivity" as a setting? Thats all I had to do for my dad for him to be able to easily use it again, on a samsung though.

There are also phones with buttons again, the unihertz titan 2 elite looks good btw. Or Clicks addon keyboards.
