New smartphones usually have two, three or more cameras on the rear side. All the cameras have a specific functionality, to create better photos or videos and improve the user experience.

For example on the back side of Samsung smartphone, there is:
  • Main camera
  • Telephoto camera
  • Wide angle camera
  • Depth camera

Sometimes the mutliple cameras can work together.
