When you snap a photo, it always focuses when you half press, and when you fully complete your snap, the camera takes a picture that it did not lock - which is very annoying. Even if the antishake is tuned on, when the subject is moving (not exactly moving, but most of the living subjects tend to move and cannot be still), the camera misses the 'locked focus' - I have raised this issue in windows phone related microsoft answers website thinking that it could be a OS issue - however, this could be a hardware / ROM issue. Iphone 4 and 4S do a great job in locking the focus and taking a snap of the locked subject.
