The Huawei Mate 20 Pro has an integrated setting within the Android system that allows you to protect your eyes when reading the display. This is the so-called blue light filter.
As the name suggests, it filters out blue light emitted by the screen.
This blue light is responsible for the fact that it is harder to read the display, especially in the dark. It will also wake you up again, which is counterproductive, especially when surfing in the bedroom with the light already dimmed.
If you are interested in the blue light filter and the functions such as schedule and color temperature, then we have summarized in the following article how to activate and use this on the Huawei Mate 20 Pro:
