Constance likes the "no blur feature" on her Samsung mobile phone camera, but after the latest phone update, it doesn't work! What can she do? Rich isn't sure what happened with the update, but she can do face tracking by using her finger to tap and hold on the face of her subject, locking the focus. There is also tracking autofocus in the camera settings. Look under the Bixby features setting icon. There's also a shot suggestions and optimizer feature.
