I can't say that I've had a problem with my N9 pics.

Here's one and here's another for instance.

I won't claim to be a photographer - I seriously don't have the photographer's eye for framing and balance - but with that much noise, it seems like you were in a place that would be a problem for the sensor to figure out if it should flash or not and the noise is too high, so it picked poorly it seems.

I would say more, but I'm amatuerish at best. You can do/find better examples to shoot in natural light, as well as not in shade as well. I suggest that you mix it up a bit and see if your pics continue down this path.

And if you've messed with the settings, reset to defaults, stick to 7mp and get away from continuous (burst) camera (that lowered the look and feel of my pics)

But you shouldn't be having any problems like you're witnessing. I've taken better, and worse, pictures with my N9.
