    I have a sony xperia xz premium, and for some reason after hanging up from a phone call, I got an error message that says:
    unexpected error. Closing application.Attempt to invoke virtual method 'org.jivesoftware.smack.AbstractXMPPConnectin org.jivesoftware.smack.tcp. XMPPTCPConnection.connect()' on a null object reference
    It keeps popping up, fading away and then popping back up.

    Smack is an API related to messaging, so it might be an error related to one of your apps that has some kind of messaging option. https://www.igniterealtime.org/projects/smack/
