No matter what it's going to suck compared to a real camera. Real cameras have lenses that are bigger ., and for good reason. Good photos require lots of light, lots of light require good lenses, and you are not going to magically be able to acquire lots of light with such a small lens.
More camera megapixels would be worse, not better
Before, during, and after the introduction of camera phones,
many people were hoping/asking/whining for a better camera in their cell phones. One with more megapixels, that is. Unfortunately, more megapixels wouldn't have made the Phone camera better. The extra pixels wouldn't help with anything, in fact, and could even hurt under some circumstances.
Giving the Phone more megapixels won't make it shoot better snapshots any more than buying an expensive car will make you rich. It's the other way around: because real cameras have better lenses, they can get good mileage out of better image sensors. The first problem with a Phone's camera lens is that it can't focus well .The Phone's lens must be able to produce a (reasonably)
sharp image regardless of the distance between the phone and the subject, because it can't adjust its focus well. There are two ways to do this: be more liberal in what's accepted as "sharp" and make the lens opening (aperture) smaller.
The Phones cameras takes pictures that are within the sharpness range expected from a 2 megapixel camera, while the aperture is a respectable f/2.8. If they were to use a higher resolution image sensor with the same lens, the pictures wouldn't be any sharper—and 2MP sharpness in a 5MP camera is just not acceptable. The other option would be to reduce the size of the lens opening, but that way, the amount of light that reaches the sensor is reduced and the Phone would have an even harder time taking decent photos under dim lighting.
The other problem is that the more megapixels that are crammed in the same size sensor, the smaller those pixels get. Since individual pixels are gathering less light, many will be "underexposed" and produce a lot more noise (see
long explanation and
examples.).
