How do I activate the camera from the lock screen?
You can do this if you first set the camera widget up in the lock screen.
Please set the camera widget on the hold screen after checking the Multiple widgets. And then you can use immediately the camera on the hold screen.
1. Setting → My device → Lock screen → Multiple widgets
You cannot use widgets on the locked screen in “Easy” mode. Feature works when in “Swipe” screen to unlock set up.
2. In Lock Screen settings, tap on Lock Screen widgets, then select Favourite apps or Camera.
Tap on Favourite apps or Camera to change the setting for Widgets used in the lock screen
Swipe the default lock screen from right to left to open Camera (or Widgets) when in the lock screen
