当您按住电源按钮时，冻结或无响应的Android设备可能不会显示电源菜单。(Android)强制(Force)重启（也称为“硬重启”或“硬重启”）设备以将其关闭并重新打开。
按住电源按钮(Power button)15-30 秒。或者，同时按住电源键(Power key)和降低音量键(Volume Down key)7-10 秒。您的手机将在黑屏上停留几秒钟，然后自动重新开启。如果没有任何反应，您的设备可能不支持组合键。尝试按住电源(Power)和提高音量(Volume Up)按钮至少 15 秒。
如果您硬重启未冻结的手机，则设备可能会在按住电源键和(Power)降低(Down)音量键时截取屏幕截图。(capture a screenshot)屏幕截图后继续按住键以启动硬重启。
如何自动重启安卓手机
长时间使用后，您的手机可能会变慢并出现一些问题。将手机配置为根据计划自动重启可以优化其性能。幸运(Luckily)的是，一些Android手机制造商（例如三星(Samsung)）在他们的设备中加入了自动重启功能。
这使您可以安排您希望手机自动关闭和重新启动的时间段（时间或天数）。
- 打开设置(Setting)应用程序并点击常规管理(General Management)。
- 点击重置(Reset)并选择自动重启(Auto restart)。或者，您可以将自动重启(Auto restart)开关移到右侧，然后点击自动重启(Auto restart)以配置自动重启计划。
- 确保打开自动重启(Auto restart)，然后选择三星(Samsung)手机应该自动重启的日期和时间。
在某些三星 Galaxy(Samsung Galaxy)机型上，进入设置(Settings)>电池和设备保养(Battery and device care)，然后点击右上角的三点菜单图标。选择自动化(Automation)并点击在设定时间自动重启(Auto restart at set times)。将On开关移到右侧并设置您喜欢的自动重启计划。
只有在以下情况下，您的手机才会重新启动：
- 它不在使用中。
- 屏幕或显示屏关闭。
- SIM 卡锁已关闭。
- 电池电量高于 30%。
注意：(Note:)自动重启功能支持开箱即用至少运行Android v5.0 Lollipop的(Lollipop)三星手机。(Samsung)即使您将旧设备升级到Android Lollipop ，您也可能无法在旧设备上找到该选项。此外，锁定到运营商的手机可能缺少自动重启功能。
取出并重新插入电池
如果您的手机有可拆卸电池并且它被冻结或没有响应，请取出电池并等待几秒钟。重新插入电池，按住电源按钮(Power button)，然后等待屏幕亮起。如果您的手机无法开机，则可能是电池没电或插入不正确。
确认电池已正确插入，然后重试。如果问题仍然存在，请将充电器插入手机，为电池充电几分钟，然后重试。
以安全模式重新启动
以安全模式(Mode)启动手机有助于诊断恶意软件感染(diagnose malware infection)并解决性能问题。在安全模式下(Mode)，Android仅加载开箱即用的手机随附的系统应用程序。在您退出安全模式之前，大多数第三方应用程序和其他无关紧要的服务都会被暂时禁用。
方法 1：将 Stock Android 启动到安全模式(Method 1: Boot Stock Android into Safe Mode)
以下是如何将运行库存Android的(Android)Pixel手机和其他设备启动到安全模式。
- 首先，您需要关闭手机。按住电源按钮(Power button)至少 5-7 秒以显示电源菜单。或者，同时按住电源按钮(Power button)和降低音量(Volume Down)键 5-7 秒。

快速重启手机
重新启动Android手机很容易。如果您的手机在重启或硬重启后仍然出现故障，请更新其操作系统或联系您的设备制造商。执行出厂重置或硬重置(factory reset or hard reset)可能会解决问题。这将删除您的所有应用程序和数据，因此请仅在用尽所有故障排除修复程序后重置您的设备。
How to Restart Your Android Phone
Restarting your phone comes with many benefits. It refreshes your phone’s oрerating systеm and fixes many performance-related issues and malfunctions in Android. Say your phone is freezing or some apps are unresponsive and crashing; a quick restart can resolve the issue.
Rebooting Android phones is easy, but the steps may vary depending on your phone’s model and operating system version. If it’s your first time using an Android smartphone, we’ll show you different ways to reboot the device.
Note: Make sure you manually close apps before restarting your Android device so you don’t lose any unsaved data.
Use Your Phone’s Power Button
Almost all brands and models of Android smartphones have a power button. Press and hold the Power button for 5-10 seconds to reveal the power menu. Afterward, select Restart to shut down the device and power it back on.
Perform a Hard Reboot
A frozen or unresponsive Android device may not display the power menu when you press and hold the power button. Force restart (also called a “Hard Restart” or “Hard Reboot”) the device to turn it off and back on.
Press and hold the Power button for 15-30 seconds. Or, press and hold the Power key and Volume Down key simultaneously for 7-10 seconds. Your phone will stay on a black screen for some seconds and come back on automatically. If nothing happens, your device probably doesn’t support the key combination. Try holding the Power and Volume Up buttons for at least 15 seconds.
If you hard reboot a phone that isn’t frozen, the device may capture a screenshot when holding the Power and Volume Down keys. Keep holding the keys after the screenshot to initiate the hard reboot.
How to Auto Restart Android Phones
Your phone can get slow and develop some issues after long usage periods. Configuring your phone to auto-restart based on a schedule can optimize its performance. Luckily, some Android phone manufacturers (Samsung, for example) incorporate an auto-restart feature in their devices.
That allows you to schedule periods (time or days) when you want your phone to shut down and restart automatically.
- Open the Setting app and tap General Management.
- Tap Reset and select Auto restart. Or, you can move the Auto restart toggle to the right and tap Auto restart to configure the auto-restart schedule.
- Make sure Auto restart is toggled on, then select the day(s) and time when your Samsung phone should auto-restart.
On some Samsung Galaxy models, go to Settings > Battery and device care, and tap the three-dot menu icon in the top-right corner. Select Automation and tap Auto restart at set times. Move the On toggle to the right and set your preferred auto-restart schedule.
Your phone will restart only when:
- It isn’t in use.
- The screen or display is off.
- SIM card lock is off.
- The battery level is above 30%.
Note: The Auto-restart feature supports Samsung phones running at least Android v5.0 Lollipop out-of-the-box. You may not find the option on older devices, even if you upgrade them to Android Lollipop. Additionally, phones locked to a carrier may lack the auto-restart feature.
Remove and Reinsert the Battery
If your phone has a removable battery and it’s frozen or unresponsive, remove the battery and wait for a few seconds. Reinsert the battery, press and hold the Power button, and wait for the screen to light up. If your phone doesn’t come on, the battery is probably flat or inserted incorrectly.
Confirm that the battery is inserted correctly and try again. If the problem persists, plug a charger into your phone, charge the battery for some minutes, and try again.
Restart in Safe Mode
Booting your phone in Safe Mode can help diagnose malware infection and troubleshoot performance issues. In Safe Mode, Android only loads system apps that ship with your phone out-of-the-box. Most third-party apps and other inessential services are temporarily disabled until you boot out of safe mode.
Method 1: Boot Stock Android into Safe Mode
Here’s how to boot Pixel phones and other devices running stock Android into safe mode.
- First, you need to shut down your phone. Press and hold the Power button for at least 5-7 seconds to reveal the power menu. Or, press and hold the Power button and Volume Down key simultaneously for 5-7 seconds.
- Tap and hold the Power off option until the “Reboot to safe mode” pop-up appears on the page.
- Tap OK to boot Android into safe mode.
Method 2: Boot Non-Stock Android Phone into Safe Mode
The procedure to boot non-Google phones to safe mode will depend on the device’s model and Android version.
For Samsung phones, power off the device and wait for 30 seconds. Afterward, press and hold the Power button, and release the button when the Samsung logo appears on the screen. Press and hold the Volume Down key after releasing the Power button. Release the Volume Down key when your phone boots into safe mode.
Alternatively, power off your phone, wait 30 seconds, and press and hold the Power and Volume Down buttons simultaneously. Let go of the Power button when your phone’s screen lights up, but keep holding the Volume Down button. Release the button when your phone boots into safe mode. Check the bottom-left corner of the screen for a “Safe mode” inscription.
Exit Safe Mode
Restart your phone normally to exit safe mode. On some Samsung phones, you may exit safe mode from the Notification panel. Swipe down from the top of your phone’s display, tap Safe mode is on, and select Turn off. That’ll restart your phone, exit safe mode, and restore all your apps.
Restart Android Using the Android Debug Bridge (ADB) Tool
If you have a Windows, Mac, or Linux computer and your phone’s Power button is faulty, reboot your phone using the Android Debug Bridge (ADB) tool. Install the tool on your computer, enable USB Debugging on your phone, connect your phone to your computer with a USB cable.
Next, open Command Prompt (on Windows) or Terminal (on macOS), type or paste adb reboot in the console, and press Enter or Return on your keyboard.

Restart Your Phone Quickly
Rebooting an Android phone is easy. If your phone still malfunctions after a restart or hard reboot, update its operating system or contact your device manufacturer. Performing a factory reset or hard reset may fix the problem. That’ll delete all your apps and data, so reset your device only after exhausting all troubleshooting fixes.
