[Way out west]

In messages, the font size seems larger than the rest of the apps. Does anyone know how to fix it?

Pinch to shrink?

I actually added that button to do it .. But it shouldn't be doing it anyway. I'm attaching another picture for reference... This is the Default font size i expect to see

I will just do a reset... That has to fix it

Did you already try the pinch-to-zoom gesture as suggested by IHateMyTreo above? That allows you to easily enlarge or reduce the font size when you're in a message thread.
