If your subject is placed off-center in the frame with a distant image in the background, your phone will try to guess where to focus. Your default camera mode will focus on the center of the picture. The image will show a sharp background and a blurry subject in the foreground. You can lock the focus on the subject and , you can recompose the shot and shoot. Then your image will be crisp and clear.

  • Busy Background Scene

For example if you see a person, car, or if there is any moment the camera will refocus on that subject changing the story of the image. To improve the image lock the image, and if the exposure is not great you can brighten or darken the image with the exposure slider.
