remove camera from lockscreen by right slide

Please don't presume to speak for ALL iPhone users. You most certainly don't speak for me. The camera and the flashlight are baked into iOS and can't be removed there. You could remove access to the camera completely in Screen Time, but that would remove access to the camera completely, so not a good solution.

You can let Apple know what you'd like to see here, but I highly doubt this is something Apple will accommodate --> Feedback - iPhone - Apple
