According to sammobile
"The new Android 4.4.2 update brings minor UI changes, the most noticeable change being the use of KitKat style white status bar icons instead of the multi-colour icons Samsung has been using in all of its devices until now. The phone has also received a performance boost with the latest update and there is an increase in benchmark scores, as well. Samsung has improved the lock-screen by adding a camera shortcut directly on to the lock-screen for quick access and while playing music the album art now shows up in full screen. Samsung’s keyboard layout has been improved for use in landscape mode, which makes gesture typing easy and much faster. Core Android 4.4.2 changes include: wireless printing, new emojis support, choice between stock messaging app and Hangouts for SMS/MMS, option for changing default launchers under settings, and more."
