Solutions:
The camera always fails to complete the focus during using, which may be caused by the following reasons:
1. The camera lens of the mobile phone is too close to focus.
MI mobile phone supports macro shooting of around 10cm (some new models support 4cm focusing mode). If the distance is too close, focus failure may occur. It is recommended to maintain an appropriate shooting distance to ensure the image quality.
2. The shooting conditions are not conducive to focusing, such as the ambient light is too dark.
3. In addition, with the update of MIUI system, the camera is being optimized constantly. To ensure better user experience and image quality, it is recommended to upgrade to the latest MIUI version.
