Went a step further than doing a factory reset - updated Android firstly from 4.0.3 to 4.0.4 then to JB. Factory reset and camera retest in between each upgrade - no major difference to the photos. If anything the pics were a *little* better but then that's checking under daylight instead of halogens. With the halogens on and me standing between the window and the photo subject - same problem, far too red. Even with the contrast and saturation turned down, anything white or brown-ish has a pinkness to it that's just not realistic, so it's going back
