Comments on CallDetector for Android

★★★★☆ J R · Aug 21, 2025
If you have telemarketed, scammers or just need to block any unwanted calls. This app works most of the time. When it doesn't the caller gets your voice mail and if they leave a message that can quickly fill the mailbox. I don't understand when a call is blocked why do they get to leave a voice mail? So it's not actually blocked.
★★★★★ Bruce Smith · Sep 6, 2024
In 2019. I wrote "I have been using Call Detector for about 30 days with success!" As of September 6, 2024, I am still successfully using and enjoying "Call Detector." My first cellphone, in ~ 2013 was from TracFone. We are pleased with their service and variety of calling plans. Their rates are more economical than those of other providers. TracFone has recently become a member of the Verizon family.

Thanks for your help. Thanks for saving my log. I uninstalled you guys. Because I was having problems with my phone. I read the reviews of Tracfone. They were having problems too. No Stars for Tracfone. So to let you know. Tracfone is having a lot of problems now. I got the Dashboard back. But that's it. You can't buy anything on Tracfone App. Will update when it happens.

Doesn't block the calls. I get calls every day, and it shows on the screen it is a spam call, but they still are able to leave a voicemail message and if I am on the phone with someone when the spammer calls it disconnects me.
★☆☆☆☆ Joseph Dana (Jo tha fixer) · Nov 13, 2025
This app used to be really good...since they changed the logo it sucks...it used to pop up when I got a call, and it would ask block it doesn't do that no more, and it lets every spam caller through even though I have every thing checked to block related to spam... I left a really good review a couple of years ago, but I had to come back and share this... please fix this otherwise it's over lol

This so-called call detector is not blocking any calls I have to block them manually by myself
