The above images were leaked from the much anticipated LG G3. They show off the all new lock screen app. The round widget will be used for clocks and much more. This is a simpler approach to a lockscreen by LG. It looks pretty sleek actually. The AOSP lockscreen addable widgets and it can seem a bit cluttered. Here all the widgets are contained into one little circle while the rest of the lockscreen is blacked out.
In the widget you get plenty of different clocks, message notifications, ability to accept phone calls, ability to view health stats, access device settings, and plenty more. Maybe we will see this in the form of a standalone app soon.
