Font size

[anon(153966)]

I increased the font size on my iPhone 7 Plus (settings \ display & brightness). Yet, it still seems not all apps, even default (Mail) is using the new font size.
As an example, if I take a photo, and then share it from the photo app to Instagram, the text it rather small.

How can I correct this?

You can try using display zoom instead, which scales up the entire interface, not just the fonts.

Unlike dynamic text, it's system level, so developers not supporting it isn't an issue.

Oddly enough, I was already 'zoomed'. Albeit, rather weird about the font size while posting to Instagram, via the Camera.
The font was small, almost smaller than I set in the Display & Brightness section. Weird...
