There are flickering gray or black dots at the bottom of the HUAWEI phone screen

Problem:

Two dots flicker on the HUAWEI phone screen when the screen brightness and gray scale are low.

Design description:

The proximity sensor and ambient light sensor are located at the bottom of the screen. When the component is working, it emits infrared light intermittently. Gray or black dots may flicker at the corresponding position on the screen, which is more obvious on the gray background. This is a normal physical phenomenon and does not indicate a screen hardware fault. The dots will disappear when the sensors stop working and will not affect display and functions. Please rest assured.
