Great news Razr HD Owners, if you haven't been able to get this to work on the Stock 4.1.2 (which I had no luck there either.) It works perfectly on 4.2.2 I have it running right now on XenonHD. It doesn't seem to replace the stock camera, either. Also, it seems I get that same "blue light" in the bottom corner of post #40. I am convinced it is a design flaw, as when the sound button is pressed to "on" the blue lights up, when turned off there is no light, just the overlap in the bottom corner of the screen.
On a further note in TiBU the apk appears as Camera 3.0.187, no need to rename just download and install.
