about the Samsung S4 being a Google edition phone, running AOSP, won't that make all those sensors and stuff for the camera to be useless? touchwiz incorporates code and processing to get good pictures. without it, it'll just be a basic camera with photosphere, like the nexus 4
i also was reading around, and someone made an interesting point. we all know android 4.3 is coming soon, which means that it may have camera improvements, which would not make the S4 camera go to waste. and the rumor about the HTC One being AOSP, it really would need improvements in the camera software, so that the One's camera wont be a waste as well. i hope that is the case
