iPhone "wins" blind shootout over flagship Android phones! This is exactly what I have experienced with Android versus iPhone. Sure on Android you'll get a technically better picture but only if you auto-focus correctly and you don't have a problem with the lock screen or invoking the camera app. The out of box iPhone experience for taking photos is so much better than any other cameraphone I have tried. And if you want manual controls you can download Camera 645 or any of the other very reliable manual setings apps and much much more! The only thing you can't get is RAW files but you can shot TIFF with 3rd party apps and the RAW files that I've tried on the Nexus 6 aren't much better than the TIFFs you get from 3rd party iPhone apps.
It would be so great if Canon, Nikon, Olympus or Sony could duplicate or even surpass the out of box Apple cameraphone experience complete with seamless uploading and editing like you can do on an iPhone. I think it's definitely possible; it's just a matter of thinking outside the traditional "real" camera box!
21st century cameras are social and on the internet and awesome-ized by software and sensors
