Why do I automatically darken the indoor environment in the camera and only highlight the scenery outside the window when I shoot the window indoors with an 800W pixel mobile phone or digital camera?

First, it has nothing to do with pixels.

Secondly, both mobile phones and digital card machines are automatic cameras, which will find a set of their own stored exposure data according to the brightness of the scene, that is, if the brightness is too large, it will automatically reduce the exposure. If the light is too small, it will be exposed automatically. So if the window in the photo is large, the brightness of the window is given priority, and vice versa.

Third, although the SLR has a manual shift (some cards do, but mobile phones generally don't), the principle of the camera will not change, so if you want to shoot both scenes, you need to use other methods.

Fourth, the so-called other methods are to fill the room with light and make the indoor and outdoor brightness similar. Digital card can try to turn on the flash, of course, the effect depends on the situation, because after all, it is an automatic camera, you can try more with different gears. The SLR should also be equipped with a flash, and it is best to add an independent photographic lamp and manual exposure.

Fifth, it is more natural to use natural light. The outdoor light is weak in the morning or at night, so it is ok to turn on the indoor lighting.
