Let the camera auto focus on the center of the screen. Or you can tap another area on the screen that you want to focus on. Face detection If you turn Face detection on in the camera settings, the camera will automatically recognize faces and adjust the focus when you're taking photos of people. When you see boxes on people's faces, tap to take the photo. Auto focus and face detection are not available when you're using the front camera.
