The problem

Steps to reproduce

What is the current behavior?

In System > About phone, SElinux status is Permissive. In Trust it shows Disabled but looks like it shows Disabled when it's not enforcing.

With an app and root access I switched to Enforcing, but the camera wasn't working anymore in Open Camera and Signal. Maybe other errors would have happen, I switched back to Permissive immediately.

What is the expected correct behavior?

SElinux should be "Enforcing" by default and without issues.
