Wow! just absolutely wow! I have had thee worst time with spam calls over the years and this app is truly a godsend. I went from maybe 8 to sometimes 15 calls a day from spam and unknown numbers — that number has fallen to ZERO. Thank you guys, your app has solved a problem in my life. 10/5 stars.
하루에 모르는번호로 전화가 500통씩오는데 이건 혁신이네요 감사합니다
Excelente aplicación, de verdad que si te bloquea todas esas llamadas que no tengas registrado en tu teléfono, pero si permite la de tus contactos registrados. Así se evita uno tantas llamadas spam o de estafas. 10/10 esta app.
Instalei ontem e voltei aqui hoje para avaliar. Realmente é eficaz… agora esse aplicativo está bloqueando todos, somente não bloqueia os números que estão salvos nos meus contatos. Parabéns! Vocês são Incríveis. Nota 1000.
Приложение монстр по защите от ненужных входящих звонков. Простое и работает. Установил вчера, ждал входящих звонков, сегодня убедился в надёжной блокировке. Благодарю, уважаемый разработчик!
tbh this is the beauty, "SSS" level app — small, smart and simple. Guys it's awesome: no menus, no ads, no options, no BS. Open the app and you have ONLY 3 tabs… never saw such a smart app. Straight to the point.
fantastico in 1 giorno... 14 chiamate silenziate tutta pubblicità... grazie
es la mejor opcion de bloqueo de llamadas fraudulentas, si hubiese 10 estrellas, les pondría, gracias por crear esta maravillosa app.
Muito bom o aplicativo. Desde que eu instalei ele, tive paz. Nem vejo quem me ligou, que não são os meus contatos. O App não tem propaganda, não precisa de login, é super prático. Recomendo demais.
Thank You Very Much, Your App Stopped more Than 60 Spam Calls Per Day!!! I have a Samsung Galaxy A14… I Have Over 1,000 Numbers Blocked and Reported. THIS APP STOPPED THEM ALL!!! GOD BLESS YOU FOR MAKING THIS APP!!!
좋습니다 너~무 좋아요 다른 앱들은 일일히 스팸 전화 번호를 입력을 해야 하는데 이앱은 스팸 전번을 입력 안시켜도 차단을 해줘서 너~무 좋아요 감사 합니다 잘 쓸께요 번창 하세요 ~good~
My phone (Samsung Note 10 on Verizon) has a built-in feature to block calls not in my contacts. It simply does not work at all. This app does! Perfectly! I was getting up to 10 spam calls per day. All gone now. Simple and 100% effective app.
I have had this app for a little while now, an I haven't gotten any spam calls.. this app seems to work really well. Thanks to Block Unknown Callers for seeing after my phone an giving me back my sanity… haha. Thanks to all!! Respectfully, VIVIAN G GENTRY 💖🙏

应用会读取或上传我的联系人吗？
不会——而且它比大多数应用做得更彻底：本应用根本没有联系人权限，从不申请 READ_CONTACTS。这得益于它的工作方式：Android 的来电筛选系统只会把那些不在你联系人中的号码的来电交给应用处理。联系人匹配是在操作系统内部完成的，所以应用根本看不到你的联系人列表，更谈不上上传。你的联系人始终安然待在它们该在的地方——你的手机里，原封不动。
应用实际需要哪些权限，为什么？
非常少：
应用不会申请访问你的联系人、通话记录、麦克风、位置、存储或短信。
我的数据存在哪里？有任何内容会发送到服务器吗？
所有内容——你的拦截/静音记录、统计数据、白名单和设置——都存储在你设备本地。没有用户账户，也没有云同步，因此没有任何可被泄露或攻破的东西。
它会读取或拦截我的短信（SMS）吗？
不会。应用没有任何 SMS 权限，只处理来电语音通话。你的短信绝不会被触碰。
我需要注册、登录或付费吗？
三者都不需要。没有账户、没有邮箱、没有个人信息，也没有订阅。安装它，把它设为你的来电筛选应用，打开一个开关，你就受到保护了。应用免费，由广告支持。
我该如何设置？
安装后，应用会请求被设为你的默认来电筛选应用——在系统对话框中点击确认即可。然后在主界面选择一种模式（拦截或静音）。这就是全部设置了，只需几秒钟。
支持哪些设备和 Android 版本？
运行 Android 10 或更新版本的 Android 手机（Android 正是从这个版本开始加入了应用所依赖的来电筛选角色）。这是一款仅限 Android 的应用。
实际上哪些来电会被筛选？
只有那些未保存在你联系人中的号码的来电。联系人中的任何人都能照常正常响铃——应用根本看不到这些来电。在陌生号码中，你还可以进一步缩小范围（见下文），并通过白名单和重复来电放行设置例外。
拦截、静音和关闭有什么区别？
这是三种主要模式：
我能把筛选范围限定为只筛选国际号码吗？
可以。在「高级设置 → 筛选范围」中你可以选择：
我能让来电静音而不是完全拦截吗？
可以——这正是静音模式所做的。来电被允许接入并保留在你的系统通话记录中，但你的手机不会响铃。如果你更愿意查看陌生来电而不是直接拒接，这是更温和的选项。你可以随时在拦截和静音之间切换。
我会不会错过重要来电——比如诊所、快递或新的工作号码？
应用内置了多重安全网，让合法的陌生来电者仍能联系到你：
白名单如何运作？
打开「高级设置 → 白名单」并添加一个号码。每条记录可以按以下两种方式之一进行匹配：
你也可以一键直接从通话记录中把某个号码加入白名单，移除同样轻松。
什么是重复来电放行，我该如何调整它？
它假定真正有急事的来电者会再次尝试。在「高级设置 → 重复来电」中，你设置两个值：重复次数（最少 2 次）和以分钟计的时间窗口。如果同一个陌生号码在该窗口内回拨达到设定的次数，应用就会自动让它响铃接通。例如，「5 分钟内 3 次」意味着某号码在五分钟内第三次来电时会被接通。
我现在正在等一通重要的陌生来电。我能临时暂停筛选吗？
可以。使用「高级设置」中的「暂停筛选」，将筛选关闭 30 分钟、1 小时、3 小时，或今天剩余的时间。之后它会自动重新开启，所以你不必记着去手动恢复。
我能查看哪些来电被拦截或静音了吗？
可以。「拦截与静音历史」界面会列出应用处理过的每一通来电，标记为已拦截或已静音并附上发生时间。在那里你可以把某个号码加入白名单、删除单条记录（支持撤销），或清空全部。
统计数据会向我展示什么？
「统计」界面把你的防护转化为清晰的洞察，包括：
你也可以从这个界面分享一份防护统计的摘要。
我能定期收到摘要而不必打开应用吗？
可以。打开「每周 / 每月报告」，即可收到一条通知，总结在该周期内有多少来电被拦截或静音。默认为每周，你可以切换为每月或完全关闭。（这需要先启用通知。）
我为什么要开启通知？
通知是可选的，但它支撑三项功能：来电被拦截或静音时的实时提醒、你的每周/每月防护报告，以及里程碑徽章。如果你更希望零打扰，可以让它们保持关闭，筛选仍然完全照常运作。
来电者会知道自己被拦截了吗？
使用拦截时，来电被拒接——来电者通常会听到忙音或被转接到语音信箱，与正常被拒接的来电很相似；不会有任何「你被拦截了」之类的提示。使用静音时，来电者的体验完全正常（他们会听到响铃）——只有你这边的铃声被静音了。
这款应用真的免费吗？有什么隐情？
它免费，并由广告支持。本文所述的核心拦截、静音、白名单、筛选范围、重复来电、历史和统计功能，都不需要任何付费版本。
