This is share of sales in the last 3 months, not share of devices in the wild. It's no surprise that iPhone's sales share plummeted the last quarter before the 5S release.
I think it is the Nokia Lumia 1020/EOS, which I've heard is more of a sham than marketing would lead you to believe. I have to admit when I've seen the commercials, I wanted one also.
Of the two pics it takes, the 5MP oversampled pics look great, but still look like cameraphone pics. The 34MP pictures though are a different beast. I took a picture of some work colleagues in the office the other day and was able to zoom in and read the place names on a map pinned to the wall a few feet behind them. I took a picture of a crowd that was gathered across the street and was able to zoom in later and crop out some decent (slightly grainy - but not awful) looking photos of people chatting as if I were stood a few feet away. The detail really is amazing compared to anything (phone based) that I've seen before.
I have no idea what half the options on my 1020's camera do, but having the option of a manual focus slider is great too. The 1020 isn't a DSLR or even probably a decent point and shoot, but it's definitely not a sham. I wouldn't carry a dedicated camera around with me, and in my experience having the 1020's camera has been great so far (I've only had it a week).
