Camera has become an important aspect of smartphones today, and most manufacturers are now pushing the boundaries to improve the photo quality even better. One of the ways to do so is by adding dual-camera setup at the back. While HTC was among the first companies to launch the One M8 with dual rear cameras in 2014, an increasing number of companies are now opting for a similar setup.
The implementation of dual-cameras, however, can be different. For instance, the HTC One M8 and Xiaomi Redmi Pro uses one camera module to capture photos and the other module to capture depth information. Once the photo is captured, one can then add DSLR-like blur effects to their photos. In case of other smartphones such as Huawei Mate 9, Honor 8, Xiaomi Mi 5s Plus among others, they use one RGB (color) sensor and one monochrome sensor to capture crisp photos with less noise, even in low-light conditions.
The LG G5, on the other hand, uses a standard lens and a wide-angle lens. Then you have the Apple iPhone 7 Plus, which uses a wide-angle and a telephoto lens to add live bokeh effects, and 2x optical zoom. The latest to join the list is the PHAB 2 Plus which Lenovo launched in India earlier today. Now, let’s take a look at here is a look at 11 smartphones that boast dual-cameras at the back, and how they work.

Lenovo PHAB 2 Plus: The smartphone boasts of two 13-megapixel rear cameras of aperture f/2.0, with Futjitsu Milbeaut ISP for AR special effects, auto-focus, phase-detection auto-focus and dual LED flash. Just like the HTC One M8, the PHAB 2 Plus uses one camera to capture photos, whereas the other measures the depth. The setup allows users to superimpose the photo with other background for double-exposure photography, or add bokeh effects to the photos after they are captured. The camera app also lets you add augmented-reality special effects to bring virtual items into your photos.
Huawei P9: The P9 was the first smartphone from Huawei to sport a dual-camera setup co-developed with Leica. While the overall functionality remains the same, unlike the Mate 9, the P9 came with a pair of 12-megapixel snappers. The setup too includes a RGB color sensor and a Monochrome sensor to capture the color information and light respectively. One notable feature missing though was the support for OIS, which is present on the new Mate 9.
Honor 8: The Honor 8 was launched in India last month, and it features a pair of 12-megapixel cameras. Again this setup includes a RGB sensor that captures rich colors, and a monochrome sensor that captures more light with increased sharpness. Working in tandem, both cameras help to capture crisper and detailed photos. The camera also features dual LED flash, hybrid auto-focus, and laser auto-focus for short range and depth-focus for long range. There is also professional mode which gives you full control over options like shutter speed, exposure compensation and more. There is also a wide aperture mode that enables you to blur background to add DSLR-like blur effects.
LG G5: The dual-camera setup on the LG G5 includes a 16-megapixel snapper with 78-degrees lens, and an 8-megapixel snapper with a 135-degrees lens. For all purposes, the 16-megapixel snapper is main camera, but the 135-degree 8-megapixel sensor kicks in when you zoom out to capture a very wide photo with a slight fish-eye effect.
Xiaomi Redmi Pro: The dual-camera setup on the Xiaomi Redmi Pro employs a primary 13-megapixel camera and a secondary 5-megapixel camera. The primary camera is tasked with clicking the photo, while the secondary camera calculates the depth. For Xiaomi, the aim is to achieve real-time hardware-level bokeh effects in photos, which is close to what you get when using a DSLR.
Xiaomi Mi 5s Plus: Unlike the Redmi Pro, the Xiaomi Mi 5s Plus comes with a pair of 13-megapixel cameras at the back with Sony's IMX258 sensors. One camera captures color images, while the other captures only black and white images. You can choose to capture pure black and white images, and color images, or choose the stereo mode, where the camera combines the output of both sensors to enhance the final color photo.
Xolo Black: The Xolo Black was an affordable smartphone with dual-camera setup launched over a year back. The setup included 13-megapixel camera and a 2-megapixel camera, which worked in tandem to offer ultra quick auto-focus (claimed to be 0.15 seconds) and depth-mapping. The cameras also came with features like UbiFocus that let users change the focus point after the photo was taken, ChromaFlash for natural looking colors, and OptiZoom for enhanced digital zoom using image processing.
HTC One (M8): The HTC One (M8) is among the first smartphones to offer a dual-camera setup at the back. Called 'Duo Camera', this setup included a 4-UltraPixel primary camera with dual-LED flash and another module, which works as a depth sensor. This sensor essentially measured the distance between objects/subjects in the frame and later allows users to change the focus in the photo.
