At the time when the iPhone X appeared on the market, it was a revolutionary device. The phone set trends on the market, and other companies have partly based on this phone, including the aspect of notch at the top of the screen or unlocking the device with the help of the face. Certainly, a similar situation will take place when iPhone XI will appear on market. The first renders showing the potential physical appearance of this device appeared surprisingly quickly.
As you can see in the attached picture, Apple will probably apply a triple camera on the back of the device. This set of cameras will have similar physical appearance to the main camera from Huawei's phones. One of the lenses is going to support Time-of-Flight technology, which allows for creating 3D models and accurate image analysis. We have to remember that there is still a lot of time to premiere of this device (three new iPhones will probably be presented in the autumn), which certainly makes it possible that the potential phone designs may change.
