Hello, I just received this (http://i.ebayimg.com/00/s/MzAwWDMwMA==/$%28KGrHqN,!n0E63WBWLpLBO7GBhPFc!~~60_1.JPG) mhl micro usb to hdmi cable I got from ebay and I'm having the above problem. As soon as I plug it in, the GS2 starts to mirror the screen on the tv pretty flawlessly, but the touchscreen almost completely stops responding. Only veeeery long stabs at the screen are occasionally registered, and the touchscreen immediately starts to work again the instant I unplug the cable. Is this a software issue? I'm on stock 2.3.6. Thanks.
