Removing camera button on iPhone lock screen How to remove the camera button on the iPhone lock screen without removing the camera from the springboard

I don't want to allow people without access to take pictures using my phone (pictures are shared automatically by iCloud)
But in the same time, I want to be able to use the camera from the springboard.

I'm searching for a native solution under iOS 8.x or later
The only way this can be done is by using Settings > General > Restrictions to disable the use of the camera completely. A side effect is that FaceTime is also disabled.

There is no other mechanism built-in to do what you want.
