So I've been running the KitKat dialer with CM11 for some time now. Something in yesterdays nightly borked my setup giving rapidfire dialer FCs, tried going back to the previous nightly and the FC's remained. Not sure I've done a full wipe since I bought the N4 and installed CM, so figured this is a sign. Wiped, factory reset in CWM and reinstalled the latest nightly... and there's no dialer installed. TelephonyProvider.apk is in /system/app and TeleService.apk is in /system/priv-app/ as you would expect, but not dialer.apk.
So I moved dialer.apk to /system/priv-app/ and set permissions to rw-r-r and all is well, except when I update via MC updater or CWM, dialer.apk is missing again. Is this normal behavior for system apps? What would the KitKat dialer have done to make the CM updater ignore the install of that particular apk? Any advice as to how to make it stick?
