I bought two touch screens from amazon,
the one is:JBtek Latest Version 3.5 " http://www.amazon.com/JBtek-Version-480 ... B00L15FOF4
the other is:JBtek 3.2 inch http://www.amazon.com/JBtek-320x240-Dis ... B00LGOS00G
the 3.2 inch one is very easy to install, but the 3.5inch has a little difficult for me,but I still made it work,but not all of the function,I can't make the touch screen work,I asked the seller,they advice me to try Kernel by myself,wating for answer. I just don't know how to do it.
