What’s up with having two cameras at the back these days? … I think it’s totally pointless. If you want to take decent photos, go get a proper camera!
“Qualcomm’s new offering called “Clear Sight” could put dual cameras in more Android phones. It’s a single module that’s already equipped with two rear cameras and low light imaging algorithms, after all, and phonemakers can simply slap it onto their devices instead of developing their own. It’s more similar to Huawei P9’s Leica-endorsed dual cams than to the iPhone 7’s in that Clear Sight is comprised of a black-and-white and a color image sensor. See, black-and-white sensors can take better images in low-lighting than color sensors can. So, the tech combines the B&W photo taken by one of the cameras with the colors captured by the other to get the best of both worlds. “
