The iOS lock screen has remained mostly the same since the iPhone was first released. There are a few little things added here and there, but nothing major. The quick camera feature was nice, as was the enhanced notification and message system. Still, there are a few features that it could use that would be nice.
The video above shows off an interesting concept. See that tray feature? It would allow for the user to quickly turn key functions on and off. Some users want to turn these things on or off quickly without having to go through the Settings menu. I think the hotspot on and off or wifi on and off could be very useful. Especially that hotspot feature. It would be nice to use it without having to navigate through menus.
