Did you know with Windows Phone 8, you can change the text size? Out of the box, that phone shows some pretty small fonts, even on a larger screen like my Nokia 920. And if you’re using an even smaller phone, the font is just that much smaller.
Settings > Ease of Access > Font Size, let’s you change the font size and this video shows that in action.
Enjoy!
