With a camera shortcut already present, you can change at least one app shortcut on your S7's lock screen.
You may have noticed two app shortcuts on the lock screen of your Galaxy S7 or S7 Edge. Samsung sets up shortcuts to the Phone and Camera apps by default, but gives you the option to change which apps appear with just a few taps.
And since you can quickly double-press the home button to launch the Camera app -- from any screen -- it doesn't really make sense to have a Camera shortcut icon on the lock screen.
Instead, set the app shortcuts to apps you actually use, such as Spotify or Facebook.
Here's what you need to do:
A preview image of your current lock screen setup will appear at the top, with the respective app icons in each lower-corner of the device's screen. Select left or right shortcut, and then pick the app you'd like to have a shortcut to on the following the screen.
Alternatively, at the top of each shortcut's page, you can turn the respective shortcut off.
With your custom apps set, you can wake your device and launch one of your apps by sliding the app icon up, towards the top of the screen.
