I have all kinds of calls coming through which I never had before this latest update . I am NOT HAPPY! What good is it to have this protection when you are letting calls go through? It's like the app could care less if you have the settings set to block calls or left them go to voicemail! The ones getting through say "allowed" or "valid number" ! It's not valid or allowed when I've blocked all calls except those on my contact list! You need to fix this!!!

Can you go to the Calls tab and go to Call Routing Settings and review your settings to make sure you have your spam calls set to Block or send to voicemail? In your phone app > three dots > settings > block numbers > toggle on/off block calls from unknown numbers if you don't want any calls but in your contacts.

The Activ Armor app does a good job blocking robo-calls, even though it turns itself off almost every day. It's nice to finally block those annoying calls. Setting are very adjustable for political calls and other types of annoying calls. The breach report is a nice touch, but setup is a little difficult as company names and descriptions are cut off. Much better than it was a couple years ago, but a few tweaks will make it great.

The call routing, flagging, blocking works just fine. I can't do much else with the app anymore, though, because it continually freezes then crashes. The device scan (just an app scan??) takes very, very long. I usually can't get to see much on the ID & Passwords tab as that is usually when the app freezes up and crashes. By the end of all that I usually am through attempting to work with it.
