OK so I took apart the Magic Pen for the HTC Flyer to see what is inside. To see what creates the magic of the magic pen. The pen is made by N-Trig and it is a very simple piece of circuitry surrounded by an Aluminum casing and powered by a battery. I mistook the aluminum casing for the circuitry. There are two pieces of circuitry and 3 pieces that make up the aluminum casing. It is fairly easy to take everything apart just unscrew everything, but I warn you BE CAREFUL because doing this can cause the two pieces of plastic that makes up the buttons can fall out easily and putting the plastic buttons back in is a pain in the *** process involving tweezers and close attention to detail, do this at your own risk bla bla I take no responsibility. However dissembling the pen fixes problems like pen skipping, vectoring, pen inaccuracy, and hovering.
