There was a time when people used roll camera to take pictures. Then people slightly changed from the roll cameras to digital cameras. Slowly the roll cameras went out of the market. With that the creativity of the mankind didn’t stop. The phones with the camera have been invented. Initially the camera phones struggled a lot to survive in the market. The reason is that people can misuse the feature. But now none of us uses the ordinary phone.
The mobile companies added many features to the camera to promote their business. These features include digital zooming, cyber shot, auto focus and many more. With the every new product the mega pixels of the camera also increases.
Today 5 mega pixel camera phone is very much common among the public. So now there is possibility of replacing the digital cameras with these high pixel camera phones. However time only can fill the answer.
