I have two questions about large screen devices:
(1) What’s the best way to detect if a device has a large screen (such as iPad & Android Tablets")?
(2) For a business app, in order to utlize the large screens, the font size needs to be adjusted.
For example, in iPhone, I can show some texts with font size 42.
And for iPad Retina, the texts should be shown with smaller font size, such as 21. How to determine the best font size for larger screens?
