Maybe i missing something but that is what i remain disappointed about in iPhone UX. I cannot find any setting that reliably makes all system font larger to point i can at least read it. Im long sighted and do not wish to reach for my glasses everytime i need to check my phone. And this issue also present on iPads as well - iOS is not friendly to those who are neither blind nor 20/20. Makes me wonder what will happen to Apples share price when they wake one day and realise that all the teenies have gotten old and buying other phones because they cant read iPhones any more.

I loved my SE (would buy another one if i could read the thing) while i had it in 2016-2017 but the screen made my eyes go downhill noticeably and the nuisance of carrying multiple pairs of glasses everywhere made me replace it for a Android phone + BigFont app and problem solved.

How can such a brilliant company(Im a mac fanboi since late 70s) still be so useless on the mobile device UX?

There have always been specialized phones for the elderly. Literally no reason why rest of the people should suffer too large devices and I know the struggle. My mother started loosing her eye sight in past 5 years and is not legally blind. At this point even my previous iPhone6+ with max font is of little help only saving feature is speech recognition.

Sure. But products targeted even at relatively small groups of mostly non-farsighted people (kids, teens, students) are not uncommon.
