What is the matter with a layer of sand on the screen of fluorite cloud camera?

There may be some dirt on the lens. Find a piece of glasses cloth or wipe it directly with a paper towel. If there is a problem, it may be that dust has entered the lens, and it is recommended to solve it after sale.

Mobile phone selfie is very fuzzy. Where is the setting?

1, focusing efficiency

Choose a good focusing mode. When shooting still, we recommend the single-point AF focusing mode, which can accurately capture what you want. When shooting a moving object, you can switch the camera's focus mode to continuous mode.

2. The lens glass is blurred

Uncover the back cover, wipe the lens with a clean cloth, or paste the lens film.

3. Pixel problem

The pixels of the front camera are generally lower than those of the rear camera, which makes people feel that the selfie is very blurred. Replace the mobile phone with high pixel.

4. The aperture is too big or too small.

The aperture is slightly larger, such as increasing to F 1 1.
