Huawei already has experience with folding phones and three cameras, so much so that it is preparing a four-camera P30 Pro for March 26, 2019, and a Mate X following this fall.
This design describes a Huawei smartphone with a triple camera configuration on the back.
One of these lenses is the ‘periskop-zoom‘ camera that is expected to debut on the P30 line this month. This camera lets you capture photos with 10x unlearned zoom technology.
Interesting is the extra screen on the back, which can be used for face-down announcements, and selfie photos with rear cameras. Having this screen at the back eliminates the need for a front camera.
