Why my iphone pictures are blurry?

My Cousin purchased the same phone, I think; it has a basic2.0 MP camera without stabilization.

It may be happen that you are not holding camera appropriatelygriping the phone at the top and bottom, at the time of taking photos keep itstill and push the button with your other thumb.

You can either try this for better pictures. You can startcleaning the tiny lens with the available clean cloth
I get finger prints on it all the time, As for picture size, the image size: 1,200 x 1,600 at 72dpi - 1,920,000 pixels -hence 2 Megapixels (1.9Mp).

Otherwise you can visit apple community forum. The link is: discussions.apple.comfor more technical details and solutions.

I hope, now you are happy.
