Probable causes and solutions:
1. Poor light: To take photos in an environment with insufficient light, you need to enable the flash, super night scene (supported by some models), or manually adjust shooting parameters (supported by some models) in professional mode.
2. Backlight scenario: Do not take photos in the backlight scenario. If necessary, it is recommended that you turn on the HDR switch.
3. Moving shooting objects: It is recommended that you manually adjust shooting parameters (supported by some models) in professional mode.
4. Lens damage: Verify that the camera lens is clean and has no dust or stains.
5. Shaking when taking a photo: Keep the mobile phone stable, and take a photo after fixing it if necessary. If your mobile phone supports anti-shaking mode, turn on this switch.
6. Focusing inaccurate: Tap the target to be focusing on the preview screen, and take a photo after the focusing frame is stabilized.
7. If the shooting distance is too short, the camera cannot focus properly and the image is blurred. It is recommended that you keep the camera at a proper distance.
