I take it you meant 22mm.
There is no easy way to compare the human eye to a mobile phone camera, and the focal lengths you mention have little to do with it.
A mobile phone camera typically has a fixed focal length and no iris diaphragm. They also have a relatively low pixel count compared to a professional digital camera.
It also has the same resolution over the whole field of view (in terms of the sensor, the optics will degrade peripheral resolution). The screen will probably have more resolution than the eye can resolve. Since there is no control on focus, and no diaphragm, the depth of field is fixed in the camera, it will be from infinity back. If you take a photo, close objects will be out of focus. A good mobile phone display will present an image to the eye with higher resolution the the eye can resolve, over a far greater viewing angle (provided you have good close in vision), but is only as good as the sensor and optics.
The human eye behaves quite differently, there are physiological effects coming into play, the brain is a clever piece of image processing hardware. The eye only has high resolution over a narrow viewing angle, but the eye moves to track objects of interest. The variable focal length of the eye allows it to stay in focus as it tracks objects over a wide range of distance. The iris also shuts down in bright conditions, which increases the depth of field. Check that out by squinting, the light drops off, but the depth of field increases. There are numerous articles on the web on this subject, so search around for a better explanation than I have offered,
