Thanks for the suggestions. She primarily uses it when out and about, so carrying around an extra device for calls wouldn't really work. In terms of zoom, do you mean Display & Brightness > View > Zoomed, because I have enabled that on her phone. Accessibility > Zoom I find pretty unintuitive, and I think her shakiness would make that a problem. I've also increased text size with Accessibility > Display & Text Size > Larger Text. I've done both of those things on my phone too, because I find it much easier to use despite not having any accessibility issues as such. Out of interest, would the max-zoomed UI on the iPad Mini make any difference to gesture detection (e.g. detecting the start of a swipe rather than a tap)? Or is that more about muscle tension when trying to hold steady for a tap on a small area causing more shakes? Could you elaborate on that?
