Recently many brands like, Huawei, LG, HTC, Apple, Xiaomi and other brands already released several smartphones with dual rear cameras. Other manufacturers are also following their steps to process dual-lens cameras. The photo effect is surely great if you use a dual-lens camera because it can reach the effect of a SLR camera.

When we choose it, we need to be sure that it’s a real one. But how do we distinguish from them?

Here is the way

Working principle: main camera processing image, the secondary camera handle the image data. Frankly speaking, the main camera is for taking photos and secondary camera is for handling the photo effect like blur back ground, reduce noise, etc.

Difference between a real dual-lens camera and fake dual-lens:

a. Among mediatek chipsets, only chipsets above MT6737T can support two cameras working at same time, so if the device is only MT6737 processorm it couldn’t support it.
b. The fastest way to judge: cover the secondary camera, the blur effect will disappear for a real dual-lens camera.
c. The dual lens will both open when working
