The best I could do to make the best of it on my N4 was use HDR mode--which of course takes time and a steady hand.No but people are saying the new HTC One has the updates to fix the camera. Sometimes it has to do with software stuff. I mean an 8 megapixel camera should be pretty good. I know it is not best, but I have seen worse too.
My major issue with the N4 pics were that they had, for lack of a better word, a "cloudy" appearance (mostly indoor pics). Photo editing helped (the punch filter) but not always, and that can be a chore. I would have been ok if the pics were even at the iPhone 4's level (even if the same 5MP).
