SELinux status is set to Enforcing in Android 4.4.x
some older apps may not work with SELinux status set to Enforcing
You can set it to Permissive with the is command in terminal. setenforce 0
I made a simple script to set it to Permissive at boot.
You need init.d support
You need to rename it first, remove the .zip
You need to put it into /system/etc/init.d I use Root Explore
set permissions to rwxr-xr-x
Your good to go now
If I helped you Cheer!
