About this app

Call Defender, a FREE spam call blocking app that has protected millions of users against malicious spam calls.

“BLOCKING”: Just turn on "Spam Database" and enjoy a life free of spam, no additional charges needed! The database is provided by HKJunkCall.

“CALLER IDENTIFICATION”: Enjoy real-time caller identification! Call Defender shows the name of public or private organizations when they are calling you. Call Defender can identify over 500 thousand HK phone numbers which include hospitals, educational institutions and so on.

The data comes from HKJunkCall Whitelist, community, Internet, websites and number owners. We DONT upload the contact books of users.

Used to be a lifesaver app, filtering out nuisance calls. Now it turns off the ringer every time it filters a call, but does not turn the ringer on again afterward. So all day I miss legitimate calls because I don't hear them. It has become a less than useless app as a result. Developer had known the problem for months, but won't fix. Absolutely no way will I set this untrustworthy app as my default calling app.

We apologize for any inconvenience caused. Because of Google's newest policy, the ringtone mode is affected. It will be fixed soon. Please choose "Block Call" in "Spam Detection Action", disable call vibration and set Call Defender as the default phone app. If you need further assistance, please tap the menu and Contact Us. Thank you. By C

Working fine for years on various phones. Suddenly it stopped working, with an error message saying that it had a bug to be fixed by the developer, on both of my Samsung A52 5G phones with Android v.12. Restarting/ re-installing did not help. Recovery with previous settings restored Call Defender operation. Developer then advised that a bug fix had been implemented in v. Tested ok.

Very effective in blocking spam calls, even better if it can be owned by one off purchase.
