the new lockscreen widgets introduced with Android 4.2, though Samsung fiddled with them a bit. The default lockscreen shows the time along with a personal message overlaid on beautiful photos pulled from TripAdvisor.
The water ripples have been replaced by a lens flare effect though, if you prefer, you can switch back to the old one or disable it all together.
The lockscreen has multiple panes, each containing one widget. The page to the right of the default one is special and can either be a list of favorite apps.
The pages to the left contain different widgets – email, Google Now, Messaging, music player, Yahoo! Finance and News and you can download apps from the Play Store that add new widgets.
There are no app shortcuts at the bottom of the screen by default – the Favorite Apps widget to the right has taken over that role, but you can enable them and have up to five easily accessible shortcuts.
You can change the greeting on the lockscreen by hitting the edit button. You can type something else, choose a different font and color. You can also disable the personal message altogether and remove the time and date info.
Another nice trick is the Quick glance option we first saw on the Galaxy Note II. It uses the proximity sensor to detect you reaching for the device and it lights up the screen that shows the time, missed call and message counters, battery charge and music track info.
