It simply work badly! It keeps notifying you of calls that get blocked, even after they try 15 times they call and call and call... Awfully difficult. I made it the default calling & phone app, it behave EXACTLY as it had been, very badly. I cannot turn on speaker phone or use your app. I'll be uninstalling your software after I finish the addition to my review. It won't work for me. Sorry. I triedyiurr suggestion, it DID NOT WORK AND DID NOT HELP. I am NOT going to help you debug your software
