Android Question problem with android settings Android 7

The user always can go to the settings manually and go into all settings.
You can not prevent android from doing this.

To a certain extend, that's indeed the way it is.

However, I wrote an application that works in "kiosk-mode" and blocks access to all settings.
Access to "allowed" settings is controlled by the app itself using the above mentioned code.

This worked flawless for android 4, 5 and 6.

It also works for android 7 with the one exception that, once in the screen for a specific setting, the user can go back to the "parent" setting using the arrow in the settings screen.

The only option I have for the moment is increasing the height of the overlay on the top section of the screen
