Personal Note : Most important usage of a camera app for me has to be good photo and good content at any point of time. Apple dominates both front and rear content, as well as at night times, and it also is pretty good in rear camera photos, and I'd say I like the front camera of iPhone more, the goldeny look it gives as compared to that of Samsung... So I think the options that some of the options that Samsung won, like Editing is not of much use....
