[Interest] How big are the Qt libraries in mobile?

[Quim Gil]

Hi, I'm helping reviewing a report on Qt done by an analyst company. 
There it says:

 > The Qt library does however add around 12 MB to the payload and
 > webkit doubles that. This will be reduced in Qt 5 which has
 > modularity, taking out non essential components of the library.

Can someone help checking what is the size of the Qt libraries in 
Android or iOS? Also, are they loading a separate QtWebKit?

Any idea of what the size can be for Qt 5 essential modules?

Thank you.
