I've been searching trough several CM and CM based ROMs threads and found that many people had this issue, but couldn't find any solution to it.
Please, I need help! Because the S3 it's not really mine... It's my wife's. She never let me do anything to it besides rooting and installing xposed framework, but as the phone was getting old and laggy I told her I could fix that with a good ol' custom rom. Now she won't forgive me about missed calls and messages because of this. HELP!
