There seems to be a massive discrepancy between the 2 sets of photos; those on wordpress look right up there with the best from phones, wheras the images on flickr look horrible (especially in comparison to the shots from the leica that are next to the lumias ones) and appear out of focus, poorly exposed and the colour balance is a bit off.
Just looking at the EXIF data from the flickr album, most of the photos have been put through quicktime, not sure why this has happened (have they been edited/compressed and why would anybody use quicktime for this function?), and looking at the data from the same album on the pictures taken by the leica camera, this was not done, which makes me a little suspicious of these photos. The other thing is in the outdoor photos from the flickr album the shutter speeds don't look right for such low light shots. Also the focus from a couple of the pictures was right in one corner of the image rather than anywhere near the middle, making them look way out of focus. I've seen some very nice sharp images in low light from the 900 and these are just a little hard to believe.
On the other hand those outdoor ones look amazing and make me want to replace my omnia7.
