Looks like you flashed the ROM without clearing caches and data.
Very strange, our beta users dont have this issue. Are you doing anything after flashing the ROM? any backups etc?
As I said, not a bug we've encountered in testing./No, some people even get it as soon as it boots up and I have seen it myself too. I dont have to install anything to get it and other times it takes a few hours to get one after I turn on wifi or bluetooth or make a call.
try t oflash it again clear dalvik and cache partition and then flash the rom
If you can provide the smali edits and what changed i will implement your fix.
