They call every day and hang up on me. Silent phone calls. I can tell you that they are trash. If you go on the play store web site and search for spoofing applications there are hundreds of them. The Play store is promoting the harassment of people. With the spoofing programs they can spoof a phone call to you with fake ID's on your caller ID. All of us need to call our state senators and state representatives to have them make it illegal to spoof phone calls. Someone needs to stop the Play Store from selling the phone spoofing apps.
