I had the Cricket App (Hiya) that blocks spam calls. I removed the App because it was silencing legit calls.
Now I have the App uninstalled and I have been getting more and more spam calls today. Also all unknown calls are still being silenced. That might be good but I was expecting a call from someone they are not in my phone but I know the number. The call was silenced even with the App removed. I held my finger on the app and chose remove.
