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.

Working well so far, for what I wanted it to do. I was getting up to 10 spam/telemarketing robo calls for debt consolidation loans at all hours...the company is spoofing numbers so no amount of number blocking helped. Since I installed this app two days ago, I can see the calls are being blocked...they can't leave a msg either. Don't even show on caller ID! Will update if anything changes, but works like a charm for me. *Not using the internet or ID/password features, so can't speak to those.

I've been using this app for a while and it was working fine. Now all of the sudden, none of the calls are showing up in the Active Armor call logs to report and block as spam. As others reported, scammers now are using toll free numbers showing up on caller ID which can't be blocked. I updated the app, cleared the cache, and even uninstalled/reinstalled and it still isn't recognizing any calls (real or spam) as none are showing for the last 2 days in the call log. Please fix this issue!
