Megapixels are *PRIMARY* to *YOU*.
You continuously misquote me and refuse to believe that more isn't always better, especially when its proven that if you keep putting more and more megapixels on a small sensor quality is degraded, capture speed is reduced and the bulk of the device increases.
There are people who would prefer a fast camera that captures ample detail(HTC One), then there are people that want a balance between speed an quality(iPhone 5S), then there are people who are willing to sacrifice some speed for extra megapixels(Lumia 1520)(Xperia Z1/Z2/Z3) and eventually come the people that have the time and need more resolution(Lumia 1020).
Then there are people who want to photograph in lowlight, where more sensitive and higher aperture cameras come into play, like the Lumia 925 and in low light environments a less sharp image is acceptable because zooming isn't as important.
Megapixels are part of an equation to make a great smartphone, or a great camera in general, it's not the primary factor in a great smartphone sensor.
And lastly more megapixels wouldn't translate into a better image always, taking into account all other things, and it also always wouldn't mean a sharper image because of sensor size constraint.
And sensitive sensors are also important depending on what you are taking an image of of a subject in bright light(lower ISO is better) and if you are shooting in lowlight (higher ISO) once again.
To my knowledge the lowest ISO on phones has been consistenly on iPhone, it can drop to around ISO 32 and the highest I've seen is on a Xperia Z1(or Z2?) which was around ISO 6400, but ISO also depends on how big the sensor is because other than that it would just result in a noisier image.
I know all this because I have experience with smartphone and photography in general, here are a few images I've taken with a Lumia 520 by editing the shutter speed, ISO and exposure:
