By default, two app shortcuts are displayed in the bottom corners of the lock screen on Samsung devices. These include the phone app (left) and the camera (right). If desired, these can be bundled together as a single shortcut or hidden completely. Samsung also allows apps to be exchanged, so app shortcuts from Facebook, WhatsApp or any other app can be placed on the lock screen.
