Free version worked great for about 6 months. Now, it is blocking calls from my contact list it previously allowed thru, and not blocking spam calls like it did before. If I want to mark a call to block, I have to pay, no thank you. Have to uninstall now. Thanks T-mo for a useless “free” service.


Spammers can get pretty crafty about how they are making calls and this means that the technology used to block those calls may not always know exactly what to look for. That is why it is important to find those calls that sneak through on the call logs in the Scam Shield app and report them. Reports sent from customers is how we learn and adapt.

You probably already did, but it is good to keep an eye on your block list in the app and on your device to ensure that numbers you know aren’t on there for some reason. Spoofing is a common tactic used by scammers nowadays so it is also possible that numbers are being reported spam when they aren’t. You can use the Scam Shield app to mark those calls as not spam so they are not blocked in the future. Something could have happened that removed the allow tag. Are you still seeing the contact marked as allowed or favorited when it is blocked? Did you check for updates on the Scam Shield app and your device software? Out of date software on the phone or app can cause inconsistencies in performance. When any of the weirdness is happening are you getting any error messages in the app or your notification bar, or are you just noticing that calls are not coming through or getting blocked incorrectly?

Having the ability to block the caller and report things as spam all is one place is pretty great, but I understand not wanting to pay for those kinds of services. You should still have the option to block callers in your calling settings. Most of the time you can go to the call in your phone’s call log and select the info icon next to it. If you block the number, you avoid future calls and if you report the number in the Scam Shield app, we can use that information to make the feature even better. 

Thanks for sharing a bit more information so we can try to figure out why that app is not working for you.
