无法旋转 iPad 屏幕是一个常见问题，通常很容易解决。但有时，您可能需要高级修复以使屏幕卡在纵向或横向模式以正确旋转。
按照以下建议和解决方案自行解决，以修复无法自动旋转的 iPad、iPad Air或 iPad Pro屏幕。(Pro)
1.检查屏幕方向锁定
首先，检查iPad 上的Rotation Lock是否处于活动状态。(Rotation Lock)您（或其他有权访问您的 iPad）的人可能不小心打开了它。这也是iPhone 、iPod touch甚至 Android(even Android)上相当普遍的问题(common problem on iPhone)。如果旋转锁定(Rotation Lock)已打开，请将其关闭以让 iPad 的屏幕再次开始旋转。
为此，请从 iPad 屏幕的右上角向下滑动以打开控制中心(Control Center)。在运行 iOS 10 或更早版本的Apple iPad 上，改为从屏幕底部向上滑动。如果旋转锁定(Rotation Lock)按钮显示为活动状态（白色背景上的红色锁定图标），请点击以禁用它。
2.使用侧面开关(Switch)禁用旋转锁定(Disable Rotation Lock)
如果您使用第四代 iPad (2012) 或更旧的 iPad 型号，旋转锁定(Rotation Lock)显示为音量增大和减小按钮上方的物理侧按钮/开关(Down)。如果您的 iPad 屏幕没有旋转，请使用它来停用 iOS 设备的方向锁定。
3.关闭屏幕，然后打开
如果旋转锁定(Rotation Lock)不是问题，您可以尝试以下快速修复。首先关闭 iPad 的屏幕（按顶部(Top)/电源(Power)按钮）。然后，将 iPad 保持在您希望它旋转的位置并重新打开它。
没运气？继续(Move)进行其余的修复。
4.强制退出应用程序
很少有应用程序会出错并阻止您的 iPad 屏幕自动旋转。要解决此问题，请尝试强制退出该应用程序。因此，从屏幕底部向上滑动并短暂按住手指以调用App Switcher。然后，将应用程序卡（例如Safari ）向上拖出屏幕。
如果之后 iPad 的主屏幕(Home Screen)开始像往常一样旋转，请重新启动应用程序并检查问题是否再次出现。
5. 部分应用不支持旋转
您很少会遇到设计上不支持屏幕旋转的应用程序。如果 iPad 的其余部分像往常一样旋转，情况可能就是这样。除了向应用程序的开发人员请求作为功能升级的功能外，您无能为力。
6. 关闭并重新启动 iPad
以下修复涉及重新启动 iPad。为此，请打开“设置”(Settings)应用并点击“通用(General)” > “关机(Shutdown)” 。然后，将电源(Power)图标向右拖动以关闭设备。屏幕变暗后，等待 30 秒。然后，按住电源(Power)按钮，直到看到Apple标志。
7. 强制重启 iPad
如果 iPad 上的屏幕出现无响应或卡住，您必须强制重启它。但是，带有主页按钮的型号和不带主页(Home)按钮的型号之间的过程有所不同。
使用 Home 键强制重启 iPad(Force Restarting iPads With a Home Button)
1. 同时按住主页(Home)和电源(Power)按钮。
2. 按住两个按钮，直到屏幕变暗并出现Apple标志。
3. 松开两个按钮并等待锁定屏幕(Lock Screen)。
在没有 Home 键的情况下强制重启 iPad(Force Restarting iPads Without a Home Button)
1. 快速按下并松开音量调高(Volume Up )按钮。
2. 快速按下并松开降低音量(Volume Down)按钮。
3. 立即按住电源(Power)按钮。
4. 按住按钮直到屏幕变暗并出现Apple标志。
3. 松开按钮，等待锁定屏幕(Lock Screen)。
8. 更新系统软件
如果问题仍然存在并导致 iPad 的屏幕冻结或持续卡在纵向锁定中，反之亦然，最好更新系统软件。这是解决自动旋转的任何已知技术问题的最佳方法。
为此，请打开“设置”(Settings)应用并转到“常规(General)” > “软件更新”。(Software Update.)然后，点击下载(Download) 并安装(and Install)，为您的 iPad 安装最新的 iOS 或 iPadOS 版本。了解如果您在更新 iPad 时遇到问题(trouble updating your iPad)该怎么办。
9. 更新所有应用
除了系统软件，我们还建议您更新 iPad 上的所有应用程序。为此，请长按App Store图标并选择更新(Updates)。然后，向下滑动帐户(Account)弹出窗格以扫描新的应用程序更新并点击全部更新(Update All)。
10.将所有设置重置为默认值
iPad 上损坏(Corrupt)的系统设置也可能是一个因素，因此以下修复涉及将它们重置为默认值。但是，这将导致您丢失已保存的 Wi-Fi(Wi-Fi)网络和隐私偏好，因此请准备好在之后花时间重新配置您的 iPad。
要重置 iPad 上的所有设置，请打开“设置”(Settings)应用并转到“通用(General)” > “传输或重置 iPad(Transfer or Reset iPad) ” > “重置所有设置”(Reset All Settings)。然后，输入您的 iPad 设备密码并点击重置(Reset)以确认。
已修复 iPad 屏幕旋转问题
上述说明应该可以帮助您在 iPad 上再次旋转卡住的屏幕。不要(Don)忘记对内存进行更直接的修复（检查Rotation Lock、关闭/打开屏幕、重新启动 iPad 等），以防您以后遇到同样的问题。
但是，如果没有任何修复工作，或者 iPad 的屏幕一直卡在横向或纵向模式，则问题可能出在陀螺仪故障上。您最好的选择是联系 Apple 支持(contact Apple Support)并预订最近的 Apple Store 访问(book a visit to the closest Apple Store)。但是，如果您愿意，您可以通过恢复出厂设置(factory resetting the device)或通过 iTunes 在 DFU 模式下重新安装固件来自(reinstalling the firmware in DFU Mode via iTunes)行执行其他故障排除。
iPad Screen Not Rotating? Try These 10 Fixes
Trouble rotating an iPad screen is a common issue that’s usually easy to troubleshoot. But sometіmеs, you might nеed advanced fixes to get a screen ѕtuck in portrait or landѕcape mode to rotate correctly.
Work your way through the suggestion and solutions below to fix an iPad, iPad Air, or iPad Pro screen that doesn’t auto-rotate.
1. Check Screen Orientation Lock
First, check whether Rotation Lock is active on your iPad. You—or someone else with access to your iPad—may have turned it on accidentally. This is also a fairly common problem on iPhone, iPod touch, and even Android. If Rotation Lock is on, turn it off to get your iPad’s screen to start rotating again.
To do that, swipe down from the upper-right corner of the iPad’s screen to open Control Center. On an Apple iPad running iOS 10 or earlier, swipe up from the bottom of the screen instead. If the Rotation Lock button appears active (red lock icon on a white background), tap to disable it.
2. Use Side Switch to Disable Rotation Lock
If you use a fourth-generation iPad (2012) or older iPad model, Rotation Lock appears as a physical side button/switch above the Volume Up and Down buttons. If your iPad screen is not rotating, use it to deactivate the iOS device’s orientation lock.
3. Turn Screen Off, Then On
If Rotation Lock isn’t the problem, here’s a quick fix you can try. Start by turning off the iPad’s screen (press the Top/Power button). Then, hold the iPad in the position you want it to rotate and turn it back on.
No luck? Move on with the rest of the fixes.
4. Force-Quit App
Rarely an app can bug out and prevent your iPad’s screen from auto-rotating. To fix that, try force-quitting the app. So, swipe up from the bottom of the screen and briefly hold your finger to invoke the App Switcher. Then, drag the app card—e.g., Safari—up and out of the screen.
If the iPad’s Home Screen starts to rotate as usual after that, re-launch the app and check if the issue recurs.
5. Some Apps Don’t Support Rotation
Rarely will you run into apps that don’t support screen rotation by design. That is likely the case if the rest of your iPad rotates as usual. You can do nothing about it except request the functionality as a feature upgrade from the app’s developer.
6. Power Off and Restart iPad
The following fix involves rebooting your iPad. To do that, open the Settings app and tap General > Shutdown. Then, drag the Power icon to the right to shut down the device. Once the screen goes dark, wait for 30 seconds. Then, press and hold the Power button until you see the Apple logo.
7. Force-Restart iPad
If the screen on your iPad appears unresponsive or stuck, you must force-restart it. However, the process differs between models with a Home button and models that don’t.
Force Restarting iPads With a Home Button
1. Press and hold the Home and Power buttons simultaneously.
2. Keep holding both buttons until the screen goes dark and the Apple logo shows up.
3. Release both buttons and wait for the Lock Screen.
Force Restarting iPads Without a Home Button
1. Quickly press and release the Volume Up button.
2. Quickly press and release the Volume Down button.
3. Immediately press and hold the Power button.
4. Keep holding the button until the screen goes dark and the Apple logo shows up.
3. Release the button and wait for the Lock Screen.
8. Update System Software
If the issue persists and causes the iPad’s screen to freeze or continuously get stuck in portrait orientation lock or vice-versa, it’s a good idea to update the system software. That’s the best way to resolve any known technical problems with auto-rotate.
To do that, open the Settings app and go to General > Software Update. Then, tap Download and Install to install the latest iOS or iPadOS version for your iPad. Learn what to do if you have trouble updating your iPad.
9. Update All Apps
The system software aside, we also recommend updating all apps on your iPad. To do that, long-press the App Store icon and select Updates. Then, swipe down the Account pop-up pane to scan for new app updates and tap Update All.
10. Reset All Settings to Defaults
Corrupt system settings on the iPad can also play a factor, so the following fix involves resetting them to their defaults. However, that will cause you to lose saved Wi-Fi networks and privacy preferences, so prepare to spend time re-configuring your iPad afterward.
To reset all settings on your iPad, open the Settings app and go to General > Transfer or Reset iPad > Reset All Settings. Then, enter your iPad’s device passcode and tap Reset to confirm.
iPad Screen Rotation Issues Fixed
The above instructions should help you get a stuck screen to rotate again on the iPad. Don’t forget to commit the more straightforward fixes to memory (checking Rotation Lock, turning the screen off/on, restarting the iPad, etc.) in case you run into the same problem later.
However, if none of the fixes work or the iPad’s screen gets stuck in landscape or portrait mode all the time, the problem could lie with a faulty gyroscope. Your best option would be to contact Apple Support and book a visit to the closest Apple Store. But if you’re up for it, you can perform additional troubleshooting yourself by factory resetting the device or reinstalling the firmware in DFU Mode via iTunes.
