Call Defender (a.k.a. Studio Kuma Call Filter ) is a FREE spam call blocking app that has protected millions of users against annoying spam calls.
“SPAM CALL 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. This feature is free if the “Charging Assistant Screen” is enabled.
