The main reason why the imaging clarity of smart phones is not as good as that of cameras.

This question is very general, and there are many correct answers according to specific reasons. It must be pointed out, however, that the current smart phone photographs are not inferior to the camera's clarity, which is also the reason why the card machine has basically withdrawn from the market.

Therefore, the problems in shooting individual mobile phones cannot represent all mobile phones. Similarly, just because one camera has a problem doesn't mean that all cameras are inferior to mobile phones.

If the photos taken by the mobile phone are not clear, there may be something wrong with its camera system, for example, autofocus doesn't work. Of course, it is not excluded that the mobile phone cannot focus because of improper operation by the operator.
