DxOMark Image Labs believes that the advent of quadruple-camera systems on smartphones is inevitable. Nicolas Touchard, DxOMark Marketing VP, recently said in an interview with a tech publication that imaging systems consisting of multiple cameras are a logical solution to transcend the physical limitations of handsets.

Larger sensors cannot be placed inside smartphones because of their compact dimensions. That is why DxOMark Image Labs believe that the rear triple-camera system seen on the Huawei P20 Pro will become mainstream in the near future.
