The Contents of "Developer Options" vanished.

[VeeHarsh]

Hi,

The contents of "Developer Options" in my Samsung Galaxy S7 Edge have vanished.
It now says "Developer options are not available for user". Along with it, I can now no longer see the notifications, or even
drag down the menus from home screen to see all the options and even the apps running in background.

Anyone has any idea as to what the problem could be and possible solution?

Thanks

I have tried tapping on the build number. But, it was of no use

Have you tried shutting it off for a few minutes, then powering up?

Tried. It seems to have no effect.

After going through all the available settings, had no option but to do a factory reset.
The functionalities are working as expected now. But, still not sure what caused that.
