When I'm trying to send the call to the voice mail, it has a long explanation of the call, with this app, I can't, because the app is covered with an add!!! So it is impossible to send it to voice mail. When this happens, it is useless to used, because the add covers it all, makes it impossible to use. It enables the caller to continue calling us. If we can't get to the controls at all, with thj adds in the way, At lease it smaller, so we can used the controls to allows us send it to voicemail.

We're sorry to hear this - please send us an email so we can get more information. Ads should never be covering interface elements so we'd like to identify and ban the offending ad. Thank you!

Good tool to help track repetitive callers and eventually block them. I've used it on my 6 year old Samsung Note 3, but doesn't work on my New Samsung Note 10, receive error trying to block. Error reporting turned on, report sent to Dev. This app is not very good at identifying these robo callers. Too many of them call again and again and are never marked as nefarious. I feel we are losing this battle until someone can get serious about stopping this. Thanks for trying to help!!
