With the increasingly rich functions of smart phones, we are more and more dependent on them. Besides using them to communicate with others and get information on the Internet, taking photos should be a feature we use very frequently. With the continuous increase of the frequency of use, users have higher and higher requirements on mobile phones to take photos.

They hope that mobile phones can have more shooting functions and bring more interesting photo taking experience. Many people even use mobile phones as cameras with multiple lenses and different functions to unlock more photo poses.

Okay

A good camera lens without a good camera algorithm is a waste of real estate on a "quad camera" device.

Trust me when I say it's just a gimmick that phone manufacturers use in getting into your pocket. I'm very sure that 80% of people use only one out of the four cameras without even knowing. Then maybe once in a while they use a second one when they take pictures with brokeh effect while the remaining two remains useless.
Funny thing is that brokeh effect can still be achieved very well with only a single camera.

A selling point
