Why do I shoot the sun with Xiaomi mobile phone and aim like this?

Mobile phone camera has automatic white balance to control exposure. Pictures with high brightness on the mobile phone will automatically reduce brightness.

You can shoot the solar eclipse directly with the camera of the mobile phone, but it is not recommended to shoot directly with the mobile phone, which has a great influence on the subsequent shooting. In addition to adding a special sun-reducing mirror, you can also place a dimming patch in front of the mobile phone lens, or place special glasses for solar eclipse in front of the mobile phone lens, which can not only achieve safe dimming, but also reduce sunlight exposure.

When shooting celestial photography, you don't need to consider the composition and other factors for the time being, because the surrounding environment is black, you just need to shoot the annular eclipse big and clear, but don't zoom in indefinitely and keep the maximum pixel.

Extended data:

Do not directly observe the total solar eclipse. Medical experts point out that "solar retinitis" in which the sun is burned by its ultraviolet rays and infrared rays for a long time is almost incurable. Macula is the most sensitive part of retina, which makes light converge and makes the image clear.

Once burned, the macula can never be recovered. You may not feel when you are burned, but you will react after a few hours, and in severe cases you will be blind. To this end, when watching the total solar eclipse, we should first pay attention to one thing: never look directly at the sun with the naked eye or any optical equipment (such as telescopes).
