请勿打扰(Disturb)( DND ) 是一项很棒的功能，可以在必要时阻止数字干扰，尤其是在您不想关闭手机的情况下。请勿打扰(Disturb)将使来电、短信和应用通知静音。需要执行需要高度专注的任务？或者您可能需要一些独处时间，不想被电话或短信打扰？请勿打扰(Disturb)可以成为您的白衣骑士。
相反，请勿打扰(Disturb)也可能是一种痛苦，尤其是当它无法正常工作时。假设(Say)您在启用“请勿打扰”的情况下仍收到电话和短信提醒。(Disturb)或者免打扰(DND)阻止您的闹钟响起。什么可能是问题的原因？
有多种情况可能会导致通知覆盖 iPhone 的“请勿打扰(Disturb)”设置。在本指南中，我们概述了与“请勿打扰(Disturb)”在 iPhone（和 iPad）上无法正常工作相关的所有可能问题以及如何解决这些问题。
1. 更改勿扰模式让您的设备静音(Disturb Silences Your Device)
默认情况下，iOS 上的“请勿打扰”只会在您锁定设备时静音您的来电和提醒。如果您希望该功能即使在使用手机时也可以使所有通知警报静音，那么您需要执行以下操作。
1. 进入勿扰模式(Disturb)设置菜单（设置(Settings )>勿扰模式( Do Not Disturb)）。
2. 在静音部分，选择始终(Always)。
如果“请勿打扰(Disturb)”在使用 iPhone 或锁定时未将来电静音，请继续执行下一个解决方案。
2.关闭重复呼叫
尽管 iOS 在“请勿打扰(Disturb)”处于活动状态时会将电话、短信和其他应用程序通知静音，但人们在多次呼叫时仍然可以联系到您。是的，重复呼叫（来自同一个人）可以覆盖您 iPhone 的“请勿打扰(Disturb)”模式。也就是说，如果对方在三分钟内给你打了两次(twice within three minutes)电话。
为防止这种情况发生，请在设备的“请勿打扰(Disturb)”设置中关闭重复通话。(Repeated Calls)
转到设置(Settings )>请勿打扰( Do Not Disturb)并关闭重复呼叫(Repeated Calls)选项。
3.禁用或调整请勿(Adjust Do)打扰时间表(Disturb Schedule)
如果您注意到“请勿打扰(Disturb)”仅在一天中的特定时间有效，请确认您没有意外设置“请勿打扰(Disturb)”时间表。转到“设置”(Settings) > “请勿打扰( Do Not Disturb)”并确保已禁用“计划(Schedule)”选项。
如果您确实设置了请勿打扰(Disturb)时间表，请确保正确配置安静时间（即开始时间和结束时间）。交叉检查(Crosscheck)首选时间和子午线名称（即上午和下午）。
4. 更改联系人状态
就像重复来电(Repeated Calls)一样，您的“收藏”联系人也可以覆盖您 iPhone 的“请勿打扰(Disturb)”配置。在您的 iPhone 上收藏某个联系人意味着该人可以在白天或晚上的任何时间与您联系（通过电话或短信），即使启用了“请勿打扰”也是如此。(Disturb)
因此，如果您在启用“请勿打扰(Disturb)”时接到来自随机联系人的电话，请检查您是否无意中收藏了该联系人。请按照以下步骤在 iPhone 或 iPad 上查看您收藏的联系人。我们还将向您展示如何取消收藏联系人。
- 打开电话应用程序(Phone app)，然后点击左下角的收藏夹。(Favorites)
交叉检查列表中的联系人并注意是否有任何奇怪/未知的联系人。
- 要取消收藏联系人，请点击右上角的编辑(Edit)。
- 单击红色减号 (—) 按钮。(red minus (—) button.)
- 最后，点击删除(Delete)以从列表中删除联系人，然后选择完成(Done)以保存更改。
5. 更改来电设置
当“请勿打扰(Disturb)”处于活动状态时，您的 iPhone 或 iPad 是否无法使来电静音？这可能是因为您已将“请勿打扰(Disturb)”设置为允许所有来电。转到“请勿打扰(Disturb)”设置，然后点击“允许来电”(Allow Calls From)选项。
确保将其设置为Favorites或No One。如果您想在“请勿打扰(Disturb)”模式下仅将来自未知号码的来电静音，则可以选择“所有联系人(All Contacts)” 。
6.重启iPhone
对于许多奇怪的 iOS 问题，执行设备重启是一种久经考验的可靠解决方案。如果“请勿打扰(Disturb)”仍然无法在您的 iPhone 上运行，请将其关闭并在几秒钟后重新打开。您还应该确保根据您的偏好启用并正确配置“请勿打扰”。(Disturb)
7.重置所有设置
请勿打扰(Disturb)应仅将电话、短信和其他应用通知静音。您的闹钟和提醒不会被静音。令人惊讶的是，我们发现一些 iPhone 用户(some iPhone users)的报告表明“请勿打扰(Disturb)”有时会干扰警报通知和声音。
如果这描述了您目前的情况，请尝试重置您的设备设置。这样做会将您设备的设置（网络、小部件、通知等）恢复为出厂默认设置。您应该注意，您的警报将被删除。
注意：(Note:)重置 iPhone 或 iPad 设置不会抹掉媒体文件和文档。
转到设置(Settings )>常规( General )>重置( Reset )>重置所有设置( Reset All Settings)，然后输入手机密码以继续。
这大约需要 3 到 5 分钟，在此期间您的设备将关闭并重新启动。之后(Afterward)，激活“请勿打扰(Disturb)”并创建一个虚拟警报。现在，检查闹钟是否在设定的时间响起。
8. 更新你的手机
如果您的手机操作系统出现问题，某些功能和应用程序可能会出现故障。很难知道“请勿打扰(Disturb)”是否由于软件错误而无法正常工作。因此，请确保您的 iPhone 和 iPad 上安装了最新的 iOS 版本。
前往“设置”(Settings ) > “通用( General )” > “软件更新”( Software Update)，检查您的设备是否有新的 iOS 更新可用。
排除干扰
请勿打扰(Disturb)就像一只听话的宠物狗，会按照信中的指示行事。正确设置它，您应该对该功能没有任何问题。您应该阅读我们的指南，了解如何在 iOS 上设置“请勿打扰”(how to set up Do Not Disturb on iOS)。
如果上述故障排除方法都无法解决问题，您应该联系 Apple 支持( reach out to Apple Support)或访问您附近的授权Apple 服务提供商(Apple Service Provider near you)，检查您的设备是否存在软件或硬件损坏。您也可以尝试将设备重置为出厂默认设置，但请确保备份文件和数据(backup your files and data)。
How to Fix Do Not Disturb Not Working on iPhone
Do Not Disturb (DND) is a great feature for blocking оut digital distractions when necessarу, especially if уou don’t want to turn off your phone. Do Not Disturb will mute іncoming calls, tеxts, aѕ well as app notifications. Need to exeсute a taѕk that reqυires deep focus? Or perhaps you need some alone time and don’t want to be bothered by calls оr texts? Do Not Disturb can be your white knight.
Conversely, Do Not Disturb can also be a pain, particularly when it fails to work. Say you’re getting calls and text alerts despite having Do Not Disturb enabled. Or DND blocks your alarm from ringing out. What could possibly be the cause of the problem?
There are various things that could cause notifications to override your iPhone’s Do Not Disturb settings. In this guide, we outline every possible issue relating to Do Not Disturb not working on iPhone (and iPad) and how you can fix them.
1. Change When Do Not Disturb Silences Your Device
By default, Do Not Disturb on iOS will silence your incoming calls and alerts only when you lock your device. If you want the feature to silence all notification alerts even while using your phone, here’s what you need to do.
1. Go to the Do Not Disturb settings menu (Settings > Do Not Disturb).
2. In the Silence section, select Always.
Proceed to the next solution if Do Not Disturb doesn’t mute incoming calls while using your iPhone or when it’s locked.
2. Turn Off Repeated Calls
Although iOS silences phone calls, texts, and other app notifications when Do Not Disturb is active, people can still reach you when they call multiple times. Yes, repeated calls (from the same person) can override your iPhone’s Do Not Disturb mode. That is, if the person calls you twice within three minutes.
To prevent this from happening, turn off the Repeated Calls in your device’s Do Not Disturb settings.
Go to Settings > Do Not Disturb and toggle off the Repeated Calls option.
3. Disable or Adjust Do Not Disturb Schedule
If you notice that Do Not Disturb only works during a particular time of the day, confirm that you haven’t set a Do Not Disturb schedule by accident. Go to Settings > Do Not Disturb and make sure you have the Schedule option disabled.
If you indeed set a Do Not Disturb schedule, make sure the quiet hours (i.e. the start time and end time) are correctly configured. Crosscheck both the preferred hours and the meridian designation (i.e. A.M and P.M).
4. Change Contact Status
Just like Repeated Calls, your “favorite” contacts can also override your iPhone’s Do Not Disturb configurations. Favoriting a contact on your iPhone means the person can reach you (via phone call or text) at any hour of the day or night, even when Do Not Disturb is enabled.
So, if you’re getting calls from a random contact when Do Not Disturb is enabled, check that you haven’t favorited the contact by accident. Follow the steps below to check your favorite contacts on your iPhone or iPad. We’ll also show you how to unfavorite a contact.
- Open the Phone app and tap Favorites at the bottom-left corner.
Crosscheck the contacts on the list and look out for any strange/unknown contact.
- To unfavorite a contact, tap Edit at the top-right corner.
- Click the red minus (—) button.
- Finally, tap Delete to remove the contact from the list and select Done to save the change.
5. Change Incoming Call Settings
Does your iPhone or iPad fail to silence incoming phone calls when Do Not Disturb is active? That could be because you’ve set Do Not Disturb to allow all incoming calls. Go to the Do Not Disturb settings and tap the Allow Calls From option.
Make sure you set this to either Favorites or No One. You can choose All Contacts if you want to silence only incoming calls from unknown numbers while on Do Not Disturb.
6. Restart iPhone
Performing a device reboot is a tried-and-trusted solution to many weird iOS problems. If Do Not Disturb is still not working on your iPhone, shut it down and turn it back on after some seconds. You should also make sure Do Not Disturb is enabled and properly configured according to your preference.
7. Reset All Settings
Do Not Disturb should only mute phone calls, texts, and other app notifications. Your alarms and reminders won’t be silenced. Surprisingly, we found reports from some iPhone users indicating that Do Not Disturb sometimes messes with alarm notifications and sound.
If that describes your present situation, try resetting your device’s settings. Doing that will revert your device’s settings (network, widgets, notifications, etc.) to factory default. You should note that your alarms will be deleted.
Note: Resetting your iPhone or iPad settings will not erase media files and documents.
Go to Settings > General > Reset > Reset All Settings and enter your phone’s passcode to proceed.
This takes about 3 – 5 minutes, during which your device will shut down and come back on. Afterward, activate Do Not Disturb and create a dummy alarm. Now, check if the alarm rings out at the set time.
8. Update Your Phone
Some features and apps may malfunction if there’s a problem with your phone’s operating system. It’s hard to know if Do Not Disturb is not working due to a software bug. So make sure you have the latest iOS version installed on your iPhone and iPad.
Go to Settings > General > Software Update to check if there’s a new iOS update available for your device.
Block Out the Distractions
Do Not Disturb is like an obedient pet dog that follows instructions to the letter. Set it up correctly and you should have no issues with the feature. You should read our guide on how to set up Do Not Disturb on iOS.
If none of the troubleshooting methods mentioned above fix the problem, you should reach out to Apple Support or visit an authorized Apple Service Provider near you to get your device checked for possible software or hardware damage. You can also try resetting your device to factory default, but make sure you backup your files and data.
