[Galaxy Tab S2 Android Development] ibot42:
There are a few denials in the log like:

13835 13835 W main : type=1400 audit(0.0:247): avc: denied { write } for name="uid_1000" dev="tmpfs" ino=3775 scontext=u:r:zygote:s0 tcontext=u:object_r:device:s0 tclass=dir

The restorecon gives some relabeling issues:

The second command worked and the first is now empty, but nothing changed with the telephony. Via wired headphone outgoing calls work, incoming calls take many seconds. Via bluetooth headset both directions don't work at all.

I also saw problems with the ringtone. When I get a call the sound (doesn't matter which one) is only played very shortly, and after that only vibration. Maybe that's part of the problem.
