I don't know if a tiny phone lens is going to pick up enough detail to use 5 MP effectively, though.I think it should move to a 8mp camera or higher. Atleast meet or excede the DX capabilities. Love android OS but kinda disappointed in the camera or maybe the material of the cover over the lense.
If your monitor is 1920x1080, your wallpaper is 2 megapixels. If you had a resolution of 2560x1600 (like on a 32"+ display), you'd have a resolution of 4 megapixels. I think that once you start getting into poster-sized photos (5MP+), the quality isn't going to get much better out of a teeny phone lens.
