http://habrahabr.ru/post/160793/#habracut how #galaxy note #stylus works. so we had those resistive screens - and we had a possibility to paint by using software like mypaint. Now, with capacitive screens we cannot paint cause - firstly, they don’t sense the pressure strength, and secondly, the precision of capacitive screens is not enough for drawing - but enough for using fingers.
What these guys implemented in galaxy note - is a new layer which allows to use styluses with new design - not just the regular stick. So this is like crutch solution - why do we need these crutch if we could just have simple resistive screen. And the answer is - because resistive screen does not work well with fingers - which most people want (and what some consider a lack of development)
