Need Help

Well that happens on my S7 Edge too; something that should not be allowed. Hope Samsung rectifies this.

However you can prevent someone from accessing and changing the settings by activating security lock features with either a fingerprint or PIN.

fingerprint lock dint help.
Hope samsung is listening to rectify this issue.

well that is a good thing that you can access quick settings from lock screen. i dont think its any kind of issue...its a sw designed to do so. because most of the time u r in hurry and without even unlocking the phone u can toggle the settings you want. hope u understand my point.

By keeping this feature you are not at all compromising your security. This feature isn't newly introduced in Nougat but exists from Android M. And idk why you can't agree on liking this feature. Supposedly if you want to put your cell on vibrate in an urgent situation would you want to go through all the locks and then scroll down to silent your phone or rather open the notification bar from the lock screen itself. Only the things which dont put you at a privacy risk are available in the notification toggle. Things which need to be secured will ask a password when tapped on it. So don't worry and please don't ask for unnecessary features.

yeah thats true.
some one can easily turn off mobile data, turn the phone silent and rob the phone which will b difficult to track
