Smart phones these days, at least the most advanced models, have begun to include dual lenses configurations at the back of the phone. This is done using a single lens (although Google's Pixel 2 has proven to be an exception).
However, Apple's iPhone can take the initiative a step further by inserting a third camera on the back. This is a report from Taiwan's Daily Economic News claiming that the iPhone 2019 will come with a triple-camera installation. Huawei has approved a similar project with the Huawei P20.
Through a combination of three cameras, phones are said to be able to capture files up to 40MP in resolution. It is not necessary for everyone to need such a high resolution, but the goal is that users should take advantage of this.
