What's the difference between real dual-touch and fake dual-touch? I have a Xperia X10 Mini Pro and by some ungodly reason it's dual touch feature is not working. I have searched around the net and I have seen here and there people use terms such as real dual-touch and fake dual-touch.
I don't really understand what's the difference here? Can the dual-touch ability be faked and how is that possible?
By the way, if anyone can tell is it possible to activate the dual touch feature in my phone I would be super thankful.
The difference between real dual-touch and fake dual-touch has to do with how the screen is built. Real touch screens have an additional layer to allow for additional inputs. There are ways to emulate dual-touch with software. This is helpful in the case of your particular phone. 

This XDA forum page has a list of updates for particular ROMs including 2 stock ROMs which enable fake dual touch.
