This happens every time I get an incoming call. I have turned off all alerts except for presidential, I tried removing the battery and sim and sd cards. I've tried clearing caches, but no matter what I do I can't get the old amber alert from august 6 to stop popping up whenever anyone calls my phone. I have to dismiss the alert to even get to the screen to answer the call. I tried calling the phone service I use (metro pcs) and they said they had seen this once before and could not resolve it at their store and wanted me to upgrade to a new phone. I currently have a kyocera hydro life.
Google searching has failed me. I don't want to factory reset yet, but I am about to try that too.
