Why does the mobile phone camera always have a large aperture but no depth of field effect?

Because the aperture of the mobile phone camera is too small, it can only be blurred by macro shooting. If it is not macro, it is almost impossible to blur the background. If you see a blurred background photo that is obviously not macro, it is definitely not taken directly by the mobile phone. Either fraud or post-processing (some mobile phone software can also handle it). And this treatment can't be true.
