There may be several reasons for the fuzziness of photos taken on the phone:
Low camera resolution. In older phone models, the quality of cameras often leaves much to be desired.
Poor lighting. If there is not enough light, the camera may not be able to cope with the task and the photo will turn out blurry.
Hand trembling. Even if your hands are not shaking, a small movement can lead to blurring of the image.
Incorrect camera settings. Make sure that the shooting mode corresponds to the lighting conditions and the distance to the object.
Image processing applications. Some apps can add a “soap effect” to photos.
Check all these points and maybe the problem will be solved. If not, then you should think about changing your phone to a newer model with a better camera.
