I used BerryPopUp for like 2 months now and trust me when i tell you there is no problem with it at all.
However, i noticed my BerryPopUp starts to stop working when I install .448 today. I tried to reinstall the app, battery pull, set the application permission and everything I can think off but still it wont pop up any message for me anymore.
bellshare does not support leaked OS's and will not address the issue. thats what you get when you install leaked OS and have no room to complain about an app not working.
install the OFFICIAL OS and see if it works, i bet it does
