iPhone 是一款非常可靠的设备，但即使是最好的智能手机(best of smartphones)也会时不时出现问题。
如果您在 iPhone 上看到明亮的白色空白显示屏，屏幕上没有显示任何图标或应用程序，您可能正面临着可怕的 iPhone 白屏死机。
就像名字听起来一样可怕，这不是一个终端问题，所以你不必出去买一个新的。
通过正确的故障排除步骤和解决方案，可以修复 iPhone 白屏，并希望您的设备能够再次使用。
什么导致 iPhone 白屏死机？(What Causes iPhone White Screen of Death?)
当您的设备由于软件和硬件故障而锁定时，会发生 iPhone 白屏死机。例如，在重摔或进水导致硬件组件故障（例如电缆松动或损坏）或由于应用程序或操作系统升级不成功而导致软件错误之后。
有时电池电量不足(low battery)也可能导致所有系统功能停止，并且 iPhone 的屏幕变白或空白。
尝试越狱手机(jailbreak your phone)时，您也可能会遇到iPhone白屏，操作失败。同样，如果您的 iPhone 较旧或已被广泛使用，则手机上可能会出现白色水平或垂直线条，表示您需要更换设备。
最后但并非最不重要的一点是，损坏的 SD（内存）卡或存储中的损坏文件可能会导致您的 iPhone 屏幕变白，或者您可能会看到仅显示Apple(Apple)标志的冻结显示。
如何修复 iPhone 卡在白屏上(How to Fix iPhone Stuck on White Screen)
无论问题的原因是什么，您都可以使用一些故障排除步骤来解决它。
1.禁用放大设置(1. Disable Magnification Settings)
在尝试其他故障排除步骤来解决 iPhone 白屏死机之前，请检查您是否意外启用了屏幕放大。您可能放大了文档或图像，这使得您的 iPhone 看起来有问题。
要解决此问题，请尝试三指点击以查看屏幕是否被放大。这样做应该将您的屏幕恢复为正常视图。如果是这种情况，请使用以下步骤禁用 iPhone 上的放大设置。
- 打开Settings > General。
- 接下来，点击Accessibility > Zoom，然后点击关闭(Off )以关闭放大。
2.硬重置iPhone(2. Hard Reset the iPhone)
如果您仍然看到 iPhone 白屏死机并且您的设备没有响应点击，请尝试硬重置。重置 iPhone 也会清除一些内存，但不会像执行恢复出厂设置那样丢失任何数据。
- 要硬重置您的 iPhone（iPhone 6 或更新机型），请同时按住Home和Sleep/Wake按钮。对于 iPhone 7，按住降低音量(Volume Down)和Sleep/Wake按钮。
- 当屏幕闪烁并看到Apple标志时，松开按钮并让设备正常启动。
注意(Note)：对于 iPhone 8 或更新机型，按下音量调高按钮并松开，然后按下音量调低(Down)按钮并松开。按住侧面（睡眠/唤醒）按钮直到 iPhone 重新启动，当您在屏幕上看到Apple标志时松开按钮。
3.将 iPhone 置于恢复模式(Put the iPhone in Recovery Mode)
如果硬重置后仍然出现白屏死机，请将 iPhone 置于恢复模式(Recovery Mode)，然后从备份中恢复。
恢复模式(Mode)有助于解决 iPhone 中的软件问题，以便您可以重新安装操作系统并从备份中恢复数据。
- 为此，请确保您有一台装有 iTunes 的电脑，然后关闭您的 iPhone。
- 将同步电缆插入手机（而不是电脑）。如果您使用的是较旧的 iPhone（6 或更早），请按住主(Home)屏幕按钮并将电缆连接到您的计算机，对于 iPhone 7，请在将手机连接到计算机时按住降低音量(Volume down)按钮。对于 iPhone 8 或更新机型，在将线缆插入电脑的同时按住侧边（睡眠/唤醒）按钮。(Side)
- 按住 iPhone 上的按钮时，会出现恢复模式(Recovery Mode)屏幕。如果您的 iPhone 屏幕变黑，则您处于恢复模式(Recovery Mode)，您可以按照屏幕上的提示从备份或更新(Update)iOS恢复您的设备。(Restore)
- 点击恢复(Restore)以从备份中恢复您的 iPhone。
4. 将你的 iPhone 置于 DFU 模式(4. Put Your iPhone in DFU Mode)
设备固件更新(Device Firmware Update)模式也称为DFU模式，可让您在不启动操作系统的情况下打开 iPhone 并规避软件问题。这样，您可以更改或重新安装 iOS。它可能听起来更复杂，但它比恢复模式(Recovery Mode)更强大。
要将 iPhone 置于DFU模式，请将设备连接到计算机并打开 iTunes。
- 关闭手机并同时按住Sleep/Power + Home 按钮（iPhone 6 或更旧版本）或Side button + Volume 按钮(Button)（iPhone 7 或更新版本）约 10 秒钟。
注意(Note)：如果按住按钮时出现Apple标志，则表示您按住按钮的时间过长，因此您需要重复此步骤。
- 10 秒结束后，松开Sleep/Power或侧面(Side)按钮并按住音量按钮。如果您看到 iTunes 徽标，则需要重新开始，但如果您的 iPhone 屏幕变黑，则说明您处于DFU模式。
- 按照 iTunes 中的屏幕提示完成该过程并检查您的 iPhone 屏幕是否再次恢复正常。
5.联系苹果支持(5. Contact Apple Support)
如果在尝试上述所有修复后，您的 iPhone 仍然出现白屏死机，您可能需要将问题上报给专业人士。通过电话或电子邮件联系Apple 支持(Apple Support)，或前往最近的Genius 天才(Genius)吧寻求帮助。
避免让 iPhone 卡在白屏上的提示(Tips to Avoid Getting iPhone Stuck on White Screen)
有时最好在问题发生之前就预防，而不是花费时间和精力试图解决它。这里有一些技巧可以用来防止你再次出现 iPhone 白屏。
- 让您的 iPhone 远离尘土飞扬的空间、潮湿的环境和暴露于环境压力的环境。
- 获取iPhone 保护壳(iPhone protective case)和屏幕保护膜(screen protector)，以缓冲重摔和进水的冲击。保护性配件还可以通过减少硬件损坏的机会来帮助延长手机的使用寿命。
- 通过对 iPhone 硬件资源（包括电池）的额外压力，请注意过热。时不时关掉(Shut)手机，让它喘口气。

iPhone White Screen: What It Is and How to Fix It
The iPhone is an extremely reliable device, but even the best of smartphones can experience issues from time to time.
If you’re seeing a bright white blank display on your iPhone with no icons or apps showing on the screen, you may be facing the dreaded iPhone white screen of death.
As scary as the name sounds, it’s not a terminal problem so you don’t have to go out and get a new one.
With the right troubleshooting steps and solutions, it’s possible to fix the iPhone white screen and hopefully your device will live once more.
What Causes iPhone White Screen of Death?
The iPhone white screen of death occurs when your device locks up owing to software and hardware failure. For example, after a hard fall or water intrusion that causes a hardware component failure such as a loose or broken cable, or software error owing to an unsuccessful app or operating system upgrade.
Sometimes low battery may also cause all system functions to cease and your iPhone’s screen goes white or blank.
You may also encounter the iPhone white screen when trying to jailbreak your phone and the operation fails. Similarly, if your iPhone is old or has been used extensively, the white horizontal or vertical lines may surface on the phone signaling that you need to replace your device.
Last but not least, a corrupt SD (memory) card or corrupt files in storage may cause your iPhone screen to go white or you may get a frozen display showing only the Apple logo.
How to Fix iPhone Stuck on White Screen
Whatever the cause of the problem, you can resolve it using a few troubleshooting steps.
1. Disable Magnification Settings
Before trying the other troubleshooting steps to resolve the iPhone white screen of death, check whether you accidentally enabled screen magnification. It’s possible that you may have zoomed in on a document or image, which makes it look like your iPhone has a problem.
To resolve this, try the triple-finger tap to see if the screen is magnified. Doing this should revert your screen to normal view. If that’s the case, use these steps to disable magnification settings on your iPhone.
- Open Settings > General.
- Next, tap Accessibility > Zoom and then tap Off to turn off magnification.
2. Hard Reset the iPhone
If you’re still seeing the iPhone white screen of death and your device isn’t responding to taps, try a hard reset. Resetting the iPhone will also clear some memory but you won’t lose any data as you would if you perform a factory reset.
- To hard reset your iPhone (iPhone 6 or newer), hold down the Home and Sleep/Wake buttons simultaneously. for iPhone 7, hold down the Volume Down and Sleep/Wake buttons.
- When the screen flashes and you see the Apple logo, release the buttons and allow the device to start up normally.
Note: For iPhone 8 or newer models, press the Volume Up button and release it, and then press the Volume Down button and release it. Hold down the Side (sleep/wake) button until the iPhone restarts, and release the button when you see the Apple logo on your screen.
3. Put the iPhone in Recovery Mode
If you’re still getting the white screen of death after a hard reset put your iPhone in Recovery Mode and then restore it from a backup.
Recovery Mode helps troubleshoot software issues in your iPhone so you can reinstall the operating system and restore your data from a backup.
- To do this, make sure you have a computer with iTunes and then turn off your iPhone.
- Plug the syncing cable into your phone (not into your computer). If you have an older iPhone (6 or older) press and hold down the Home button and connect the cable to your computer and for iPhone 7, press and hold the Volume down button while connecting the phone to your computer. For iPhone 8 or newer models, hold down the Side (sleep/wake) button while plugging the cable into your computer.
- While holding down the button on your iPhone, the Recovery Mode screen will appear. If your iPhone screen turns black, you’re in Recovery Mode and you can follow the prompts on your screen to Restore your device from backup or Update iOS.
- Tap Restore to restore your iPhone from backup.
4. Put Your iPhone in DFU Mode
Device Firmware Update mode also known as DFU mode, allows you to turn on your iPhone and circumvent the software problem without starting up the operating system. This way, you can make changes to or reinstall iOS. It may sound more complicated but it’s more powerful than Recovery Mode.
To put your iPhone in DFU mode, connect the device to a computer and open iTunes.
- Turn off the phone and hold down either the Sleep/Power + Home button (iPhone 6 or older) or the Side button + Volume Button (iPhone 7 or newer) simultaneously for about 10 seconds.
Note: If the Apple logo appears as you hold down the buttons, it means you’ve held it for too long so you’ll need to repeat this step.
- After the 10 seconds are over, release the Sleep/Power or Side button and keep holding down the Volume button. If you see an iTunes logo, you’ll need to start over, but if your iPhone’s screen goes black, you’re in DFU mode.
- Follow the on-screen prompts in iTunes to complete the process and check if your iPhone screen is back to normal again.
5. Contact Apple Support
If you’re still getting the white screen of death on your iPhone after trying all the above fixes, you may need to escalate the issue to the professionals. Contact Apple Support via phone or email, or head over to your nearest Genius bar for help.
Tips to Avoid Getting iPhone Stuck on White Screen
Sometimes it’s better to prevent a problem before it happens rather than spending your time and effort trying to resolve it. Here are some tips you can use to keep you from getting the iPhone white screen again.
- Keep your iPhone away from dusty spaces, damp surroundings and exposure to environmental stress.
- Get an iPhone protective case and screen protector to cushion against the impact of hard falls and water intrusion. Protective accessories will also help prolong your phone’s longevity by reducing the chances of hardware damage.
- Watch for overheating through extra stress on your iPhone’s hardware resources including the battery. Shut down the phone now and then to give it a breather.
