my one isn't defective-that seems to be your argument or defense mechanism everytime there is an area where the One camera falls short in comparison with another. I've taken some very good pics with it. It simply doesn't have the range, depth, whatever of the GS4. I'm not saying that it is bad, but people should know what to expect going in. For instance, in the attached pics there are alot of details that are lost on the HTC One pic. You can't even read the Explorer logo on the mirror of my wifes car. There is no detail on the tree in the background and the vehicles in the background are blurry, grainy, etc., whereas the GS4 displays them perfectly. I'm not arguing that the One is an inferior camera overall just in some situations where you might want a little more background detail it falls short. For me being in construction and it occasionally being important to get a very detailed photo of an item that may be 20' in the air from the ground it can be an advantage for the s4 *to me*. Especially when the pic may need to be zoomed in on with the least loss of detail and grain possible. Overall, both are really, really good and you can't go wrong. Just a few years ago other than Nokia nobody put out a phone that would have been even close to these. While still not even close to a good point and shoot things have really come a long way.

You said your one "was a grainy mess" which would be defective. What you posted isn't defective.
You said take the same image - but you haven't done that. You may have stood in approximately the same place, but due to the fact that the cameras have different focal length lenses, the image is not comparabe. You are able to read the logo on the mirror in the S4 vs not in the One due to the relative size of the object in the photo. The one has a wider lens and therefore all objects appear farther away than the s4. Same as saying you take a picture with a dslr with a wide angle lens and a zoom lens. Obviously, the zoom lens would allow you to read details of a sign further away. If you retake the pictures where the mirror is the same size in the resulting photo, you would see they were very similar. They will never be exact because of different focal length. Same goes for the trees. Look at the detail level in the trees further back in the S4 picture, they loose detail as well.
It is just like when I posted my examples with excellent detail, you said the s4 would have more detail. It wouldn't, if taken with the objects at the same size in the resulting photo and posted online.
Now, for you, the additional focal length could be important as you may be taking pictures from where you can't get closer to get the equivalent view. So, I would have not disputed what you said if you said you found the focal length of the s4 preferable (and the need to crop). Of course the opposite could be true for others- they need more coverage of a scene and can't move further away. But that isn't what was said. What was said is
