Hi,I have an old HTC VIVA mobile which is almost 4 years old. I want to buy new one. I am looking around.I have a question about touch screen form i read for newer mobiles now. My mobile says, it has resistive touchscreen where as new mobiles usually say, they have capacitive touchscreen. My question is, what is a difference between resistive and capacitive touch screen? What difference does it make to the phone?Thanks.
