Can someone spesify which pin is ground and which is voltage, can't find that information anywhere. I'm planning to order this kit (i9300 version) from Ebay http://www.ebay.com/itm/Qi-Wireless-...item2eca536173 I assume that that isn't plug'n'play solution even when pins are in "correct" order? I think my first try will be made without soldering with copper- & electric-tape and wires. E: ofc it can't be plug'n'play, orientation of pins are different in S3.
