What is the difference between the quality of mobile phones and SLR photos?

I took this with my mobile phone. The pixel of my mobile phone is130 thousand. Maybe this pixel is not particularly high, but it is not very low.

The photos you take can be seen, but you can't look closely. The whole picture may look good and beautiful, but if you enlarge the picture and look at it again, you will find that the whole picture is actually paste, that is to say, there is no clear border, and it is thick lines from a distance, lacking the desire for people to look carefully and not very attractive. This is basically that most photos taken by mobile phones have no post-processing feeling. Close-up shooting is ok, it may be very clear, but once the whole picture is enlarged, it will become very bad, because the focus of the mobile phone and so on are fixed, so once you want to take a bigger picture with it, it will be difficult to achieve.

These two pictures were taken with a SLR, but they are not the original pictures. They may be a little mushy. However, the photos taken by SLR have an obvious feature, that is, there is a complete and clear visual line regardless of distance, that is to say, it may be particularly clear at a certain level in the picture, but it is not so clear before or after its focus level. There is a clear sense of hierarchy, and it will not be as peaceful as the photos taken by mobile phones. The whole picture is visually comfortable.

If you shoot the same item with a mobile phone and a SLR, you will find that there may be little difference between the mobile phone and the SLR, but once you put the two original pictures on the screen at the same time, you will find that watching TV with a mobile phone may look like a money-saving version, while shooting with a SLR looks like a member can watch 1080P.
