No logging on Samsung stock ROM (Galaxy S5 Neo SM-G903F, Android 6.0.1, rooted, SE for Android enforcing)

[koebiii]

Is there any idea of how to make network log work within the above mentioned environment?

Workaround advice on Google Play ('You can disable SELinux enforcing by executing 'setenforce 0' in a root shell.') does not work.

What needs to be done, and how could I contribute to help solving this issue?

Thanks!
