Today at about 4:23pm my phone went off and when I looked at it, it showed my name and number and voicemail. I answered it but did not say anything, there was nothing on the other end, then I hung up. Not sure if this means my phone has been compromised or a hacker is working on it but am trying to research it now.  It would be nice if there was more information to your response since that may answer my concerns.
