Nokia :: E71 Supposed To Be 3MP Camera

Is there any way of getting the E71's camera to take a good quality picture?It's supposed to be a 3MP camera. But I've tried printing off standard 6x4 prints of pictures I've taken (in good lighting conditions), and yet the pictures are blurry will blotchy colouring - they look like they were taken on a poor quality VGA camera.
I've checked, and the camera is set to take pictures of the highest resolution available. What I have noticed, is that a lot of the pictures come out as files which are less than 350KB in size, which seems a very small file size for a picture taken with 3MP resolution.
To compare, I've looked at some pictures taken on my LG Viewty, and they are all on average about 1.6MB in size. As that is a 5MP camera, and working it back, pictures taken on a 3MP camera should come in at just under 1MB.Seriously, my old Nokia 6630 from 5 years ago made much better quality prints with it's 1.3MP camera, and that just doesn't seem right.
