It also has to do with physical sensor sizes that phone manufacturers define.
A 4MP sensor would be almost as big as a 5, so manufacturers that can fit a 4MP sensor, go for a 5 instead. 3.2 and 2 are almost the same, so manufacturers opt for the 3.2 now which has replaced the 2MP sensor.
An 8 slightly larger than the 6, so why bother?
I would much rather this dumb megapixel race end, and I'd rather have low-light/no-light capabilities than a 12MP sensor with a tiny lens!
With how small these lenses are, 5MP should be the max. Give me Nightshot, or a 12800 ISO setting instead.

I tend to agree on the whole. They should keep increase MP sizes but not so close to main stream digicams - for example 12-14MP is the current size of digital compacts - so 8MP is well and truly large enough for cameraphone.
8MP the size of a current 12MP would have less noise and better lowlight performance.

Hey max, right? I mean I wouldn't mind having 12mp on my phone, but not if it takes worse shots than a 10mp point and shoot.
It just becomes a waste of storage.

I'd be happy with the same size pics (2.5-3MB), but a lower pixel count so that an 8MP sensor is the same physical size as current 12MP but with larger pixels (and therefore less noise) and less compression on the final jpeg.

^^^ That's why I shoot with the interpolated 8 MP mode on my old i-mobile 902. It enlarges the photo before compressing it into a JPEG file. After downloading the photos to PC I shrink the photo down again to 5 MP and save with minimum compression in the JPEG. This way I end up with no artifacts. Pity that the white balance is so poor and the rest of the phone is crap - close to unusable

I think the megapixel number the phones have is something to do with there screen res aswell, probley why there is only 1.3 , 2mp , 3.2mp , 5mp , 8mp , 12mp , where on a digicam you can get anything where your more likely to print them off and view them on a proper screen i have a 7.1mp canon ,also phone & digicam manufactures want to get the maxium megapixels than can on the sensor. if a bigger sensor and proper lens are used then the results are alot better i use a casio EX-Z1080 it has a 1/1.75" 10mp ccd sensor and some special lens, results are below.

Mega-pixels are a double edged sword, they give useful resolution if you want to crop your photos. But if lots of mega-pixels are crammed on a tiny sensor, like the ones on phones and compact cameras, then the sensor won't get a good signal and you will get noisy images at even the camera's lowest sensitivity.
Ideally the sensor manufacturers should aim to get the best quality in daylight conditions, with little noise, camera phones and compact camera's wont get good results in low light.
