几十年来，安全模式一直是解决计算设备系统问题的主要方式。(computing devices)不出所料，当您的Android(Android)设备也运行时，它会派上用场。
在安全模式下启动您的Android手机会禁用第三方应用程序的运行。安全模式(Mode)可帮助您诊断Android操作系统的任何问题，帮助您查明问题的根源。
但是，您究竟如何在安全模式下启动Android ？在您的设备设置中或正常启动期间，没有直接可见的安全模式选项。要启动到安全模式，您需要使用不同的方法。以下是有关如何执行此操作的详细概述。
什么是安全模式(Mode)，它有什么(How)用处(Useful)？
您可能已经在智能手机上安装了各种应用程序。通常，这不会造成任何问题，因为开发人员会针对手机硬件优化大多数应用程序。但是，有些应用程序制作不佳，并且可能存在可能破坏系统稳定性的错误和故障。
如果您的Android手机开始死机或无法像以前那样流畅运行，则可能很难找到罪魁祸首。故障是由于Android操作系统本身或您下载的应用程序之一出现故障吗？
这正是安全模式(Mode)派上用场的地方。将Android(Android)设备启动到安全模式只会加载系统应用程序和服务，从而阻止第三方应用程序的激活。如果您的Android在安全模式下完美运行，则证明问题出在另一个应用程序上，您可以将其卸载(uninstall)。
在任何 Android 手机上(Any Android Phone)启动进入安全模式(Boot Into Safe Mode)的步骤
以前，不同制造商实施安全模式的方式存在差异。(Mode)您必须联系公司的客户支持以了解特定智能手机型号的确切流程。
但是，从Android 6.0 Marshmallow开始，该过程已经标准化。现在，所有运行Android 操作系统(Android OS)的手机都可以使用相同的方法启动到安全模式。无论您拥有三星 Galaxy(Samsung Galaxy)、Google Pixel还是任何其他智能手机品牌（如索尼(Sony)或 LG），步骤都是一样的。
- 按住智能手机的电源(Power)按钮。对于像Pixel这样的设备，您可能需要同时按下电源(Power)按钮和音量增大按钮。将出现电源菜单的常用选项。
- 不要点击关闭电源(Power)选项，而是点击并按住图标。您也可以使用重新启动(Restart)选项来执行此操作。
- 现在应该出现安全模式提示。(Safe Mode)根据制造商的不同，它的措辞会有所不同，但要点是相同的：点击确定以确认并让您的手机在安全模式下重新启动。
这一切都很好，但是旧的Android手机呢？除了访问制造商的网站以查找特定于设备的方法外，还有另一种通常适用于大多数Android设备的方法。
- 正常关机。
- 按住电源(Power)按钮，直到制造商的徽标出现在屏幕上。
- 现在，此步骤因设备而异。对于某些型号，仅按住降低音量按钮就足以启动进入安全模式。在其他情况下，您需要同时按住电源和降低音量按钮。
- 通过屏幕左下角出现的“安全模式”字样，您将知道您已成功。
如何关闭安全模式？
安全模式对于解决您的Android设备问题非常有帮助，但您不想永远陷入该模式。那么如何退出安全模式呢？
这很简单——只需重新启动手机，它就会自行以正常模式启动。在某些型号中，您甚至可能会在主屏幕上看到通知或弹出窗口，让您以这种方式退出安全模式。
何时以安全模式启动您的Android(Safe Mode)设备(Android Device)
如果您发现您的Android手机无法正常工作，可能有很多原因。手机的硬件可能出现故障，或者Android 操作系统(Android OS)本身可能存在问题。但通常，问题根源在于第三方应用程序。
在安全模式下启动您的 Android 是确定问题根源的一种简单方法。如果您的设备在安全模式下工作正常，则可能是已安装的应用程序导致冲突。应用程序甚至可能是恶意软件，在这种情况下，您应该立即将其删除(remove it immediately)。
如果您最近在问题开始之前安装了某个应用程序，请尝试将其卸载。当这无法解决问题时，您需要尝试更激进的方法。您可以继续卸载应用程序以找到罪魁祸首或执行重置。出厂数据重置(factory data reset)会将手机恢复到出厂时的状态，从设备中删除所有第三方应用程序和数据。
How to Start Your Android Phone in Safe Mode
Safe mоde has been a staple for troubleshooting system problems in computing devices for decades. Unsurprisingly, it comes in handy when your Android device is acting up as well.
Booting your Android phone in safe mode disables third-party apps from running. Safe Mode helps you diagnose any issues with your Android operating system, helping you pinpoint the source of the problem.
But how exactly do you start Android in safe mode? There is no safe mode option directly visible in the settings of your device or during normal startup. To boot into safe mode, you need to use a different method. Here is a detailed overview of how to do so.
What Is Safe Mode and How Is It Useful?
You have probably installed a variety of apps on your smartphone. Usually, that shouldn’t pose any problem, as developers optimize most apps for phone hardware. Some apps, however, are poorly made and may have bugs and glitches that can destabilize your system.
If your Android phone starts freezing up or doesn’t work as smoothly as before, it can be hard to find the culprit. Is the glitch due to something faulty with the Android operating system itself or one of your downloaded apps?
That’s precisely where Safe Mode comes in handy. Booting an Android device into safe mode only loads system apps and services, preventing the activation of third-party apps. If your Android performs perfectly in safe mode, it proves that the problem lies with another application, which you can then uninstall.
Steps to Boot Into Safe Mode on Any Android Phone
Previously, there were differences in how Safe Mode was implemented by different manufacturers. You had to contact the customer support of the company to learn the exact process for your specific smartphone model.
Starting with Android 6.0 Marshmallow, however, the process has been standardized. All phones running the Android OS can now be booted into safe mode with the same method. Whether you own a Samsung Galaxy, a Google Pixel, or any other smartphone brand like Sony or LG, the steps are the same.
- Press and hold the Power button of your smartphone. For a device like the Pixel, you might have to press the Power button and the volume up button at the same time. The usual options of the power menu will appear.
- Instead of tapping the Power off option, tap and hold the icon. You can do this with the Restart option too.
- The Safe Mode prompt should now appear. It will be worded differently based on the manufacturer, but the gist is the same: tap OK to confirm and have your phone restart in safe mode.
That’s all well and good, but what about older Android phones? Apart from going to the manufacturer’s website to locate the device-specific method, there is another way that usually works on most Android devices.
- Switch off your phone normally.
- Hold down the Power button until the manufacturer’s logo appears on the screen.
- Now, this step varies for different devices. For some models, holding down the volume down button alone is enough to boot into safe mode. In others, you need to hold both the power and volume down button simultaneously.
- You will know you have been successful by the words “Safe Mode” appearing at the bottom-left corner of the screen.
How to Turn Off Safe Mode?
Safe mode can be quite helpful for troubleshooting problems with your Android device, but you don’t want to be stuck in that mode forever. So how do you exit safe mode?
It’s dead simple—just reboot your phone, and it will start in normal mode by itself. In some models, you might even notice a notification or popup on your home screen, allowing you to exit safe mode that way.
When to Boot Your Android Device in Safe Mode
If you notice your Android phone not working correctly, there can be many reasons for it. The phone’s hardware might have developed faults, or the Android OS itself may have issues. But usually, it is a third-party app at the root of the problem.
Starting your Android in safe mode is an easy way to determine where the problem stems from. If your device works fine in safe mode, it is likely an installed app causing conflicts. An app might even be malware, in which case you should remove it immediately.
If you recently installed an app before the problems started, try to uninstall it. When that fails to fix the problem, you need to try more radical methods. You can either keep uninstalling apps one by one to find the culprit or perform a reset. A factory data reset reverts the phone to the condition it shipped as, removing all third-party apps and data from the device.
