If you've recently got yourself a Samsung Galaxy S3 Android powered smartphone you may have noticed that the lock screen typically features some icons at the bottom of the screen. On most other (older) Androids these icons aren't present however they act as easy to access shortcuts which allow you to jump immediately from a lock screen to the app in question. What this effectively means is that you don't need to unlock your phone, scroll to the app you want to use and select it instead you just need to use the shortcut.

So the next question is "How do I use them?" Well that is an easy question to answer. To use the "Shortcuts" on the lock screen you simply need to hold your finger on the relevant icon (for this example I'll be using the "Camera" icon) then swipe, or drag, the icon for a second or two into the middle of the screen.

After swiping the shortcut icon you will instantly be taken to the app you wanted to open. As you can see in the image to the right I dragged the Camera icon which then
opened up the Camera app (as seen on the left).

You are actually able to select which icons appear as shortcuts, allowing you to have shortcuts to any app that's on your phone. If you wish to change the shortcuts then give this guide a read.
