If anyone is interested, i have issues with the contacts crashing and phone freezing (not on my car bluetooth though, strange) , i copied my original csc files in recovery and nothing changed after reboot (lots of xposed mods didn't apply though. Hmm, another reboot fixed that). When i copied the files from lib, the contacts now work with no issues, i have yet to receive a call, though since i did use my original files it should work.
Could someone with the contacts/phone call issue copy just the lib files from their own stock rom and report back? Maybe copy one lib file at a time, if your bored?
