As the title suggests, I don’t understand how this works.

On a mobile device, moving parts are generally highly undesirable, so an interchangeable lens system can’t be used.
Instead, multiple cameras as used to provide the benefits of multiple lenses, allowing for features such as wide angle shots or telephoto lenses to be available.
Different cameras have different lenses with different qualities. Some have wide angle lenses, some have telephoto lenses, some may be black&white only but higher resolution (since it doesn’t need colour data), and so on.
This gives the phone’s software multiple different views of the same image, and allowing it to produce a better image in the long run. The black and white camera really gets sharp detail, the telephoto lens gets good information for what you’re looking right at, and so on. Put that all together to make a better photo.
These lenses can’t be replaced, don’t move, etc on their own. They’re effectively permanent. So just having telephoto and wide-angle options on the same phone at the same time is an interesting problem. This is the solution.

Unlike a big bulky camera that would be used for professional photography, there isn’t that much room for large lenses on a smartphone, nor much room for those lenses to move around to focus. Having multiple cameras allows:
* Different focal lengths i.e. wide and zoom
* Smart image filters. By taking the same photo from two slightly different angles, we can calculate a lot of information about depth, focus, and allow us to get a sharper image.
* Different spectrum sensors such as color and infrared. Used with the already mentioned smart image filters these can give even more data that allows to do more cool processing on the image.
When you zoom in with your phone and take a picture, your phone just crops the image. If you want to properly zoom in without compromising the quality of the image, you’ll need to either move the lens or use a more powerful one. Using multiple cameras is easier than a telescoping lens on a mobile phone.
If you have multiple cameras on your phone, you can cover one with your finger to see which one is being accessed, then zoom in. At a certain point, your phone will switch to a different camera.
