Oppo Under Display Camera UI
The under-screen camera has always been one of the goals of the development of smartphones. In recent years, some experimental products have also appeared. For example, Nubia, OPPO, etc. have launched prototypes of under-screen cameras, and ZTE has also launched Axon 20 5G mass-produced model, but the results are not very satisfactory.

As can be seen from the figure, to adapt to the camera under the screen, OPPO has cleverly placed notifications and signal icons in the position of the camera. The outer circle may be the battery, to avoid the abrupt display caused by the color difference of the camera position.
In April this year, digital blogger Digital Gossip Station broke the news that OPPO was developing a fully non-porous phone with an under-screen front camera and a rear camera with electrochromic technology, and to achieve a fully non-porous design, the machine also used side pressure-sensitive buttons.
