Smartphones have come a long way ahead in the areas of advancement and technology. Back to the day from single core processors to dual & multi-core processors, from single SIM to dual SIM and now from single camera to dual cameras or dual lens camera smartphones.
A Smartphone with dual camera has two separate camera lens, each having their own sensors and both these camera are placed side by side on the rear or may be further apart in some phones. Dual camera smartphones are very new in the market and there are only few of them as of now. The idea behind the dual lens camera is to improve the functionality of camera and image quality of the picture taken by a smartphone, So that the quality of pictures look comparable to the ones taken by a DSLR camera.
How Dual Camera Works in Smartphone?
In a dual lens camera setup one camera is used to take the pictures and the other one is to capture the depth of field. You will also get faster Auto-focus (AF) with dual lenses and you can also refocus the picture even after you have captured the shot. With a dual lens camera you can also enable the 3D effects in the pictures making them look more visually appealing and astonishing.

So for Dual Lens Camera System in a Smartphone
First Camera Lens – For taking regular shots / pictures
Second Camera Lens – For adjusting depth of field
Both these Camera lenses may or may not be of same Megapixels but they are definitely of different focal lengths.
To know more about depth of field see the image below:
The image on the left side has less depth of field and on the right has greater depth of field. This is because in the right picture you can see the second horse in the background very clearly which looks blurred out in the left picture.
Advantages of Dual Lens Camera in Smartphones
Here are some of the advantages of having dual camera setup in a Smartphone.
Greater Depth of Field in Pictures
With dual lens setup you will get wider aperture if both cameras are working together. It allows more light to pass through the lenses to the sensor resulting in greater depth of field in the pictures. Here as I have explained above also that the one lens is used to capture the image and the other one is used to control or adjust the depth of field.
Dual lens camera with give you faster or almost instant Auto-focus (~ 0.1 seconds) which is not possible in single lens camera smartphone.
Smartphones with dual camera can allow you to refocus the picture even after the shot has been taken. The secondary camera helps to perform refocus functionality. You can also create the bokeh effect by using the secondary camera lens by blurring the out of focus parts or background of a picture. Well the smartphone camera software also plays a large part in creating this effect.
Better Picture Clarity
It has been said that Dual Camera Smartphones takes better quality pictures especially in low light conditions. This is because dual lenses allow more light to pass to the sensor which results in better picture clarity in areas with low light. With dual lens camera you will also get very good HDR images. A dual camera can also boost the pixel size which helps in capturing cleaner images (with lesser or negligible noise) as compared to the ones taken by single lens camera. It has also been seen that dual camera smartphones generally comes with dual LED flash for taking better and clearer pictures in the night.

Disadvantages of Rear Dual Camera Smartphones
The only disadvantage I have to tell you about the dual lens camera phones or especially the rear dual camera phones is that video recording is not that good in phones having rear dual camera lens system. They might excel at capturing still photos or images but they may lack quality in video recording department.
