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. You may want to pick up a call from the hospital even if you are in the middle of a important meeting, right? The data comes from HKJunkCall Whitelist, community, Internet, websites and number owners. We DONT upload the contact books of users.

“REALTIME DATABASE”: The system checks the database every 10 minutes, and updates to the device when there is a new spam number, effectively eliminating all spam calls that frequently harass people.

Call Defender provides the simplest way to block unwanted calls and protect your privacy with ease. Call defender also lets you know who is calling using our comprehensive global database with over 700 million numbers.

Disabled my GPS by showing an on-top full screen ad with a tiny close button and eventually activated the fingerprint protected screensaver after receiving a call during a drive, forcing me to take both my hands off the wheel and eyes off the road when I was going 110km/h. It is going to kill either me or someone else one day, not to mention a potential $5000 fine and 10 demerit points. I have no choice but to uninstall it. Shame. It was my favourite app a few years ago. Ad design with no brain.

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
