The force rotate feature will not work on apps that do not support landscape view. Only the iPhone 6 Plus, 6S Plus, 7 Plus, and 8 Plus can rotate the iOS Home Screen. Therefore, there's no possibility of a landscape Home Screen on iPhone X or later, likely due to the Face ID camera position.

Use a Video Rotation App

One of the main reasons people want to rotate the screen on their iPhones is to watch videos in the correct format. Of course, videos are naturally better in landscape mode, but the nature of smartphones means many people record their videos in portrait instead.

It's easy to rotate videos from the Edit option in the Photos app on your iPhone. But not everyone keeps their videos in this app. Thankfully, some third-party apps on the App Store allow you to rotate your iPhone videos from portrait to landscape and vice-versa. One of the best video rotation apps on iOS is Video Rotate Flip. It's free to use with ads, which you can remove with a one-time fee of .99 cents.

Once you've converted your video from portrait to landscape in the app, it will export a copy to your iPhone's Camera Roll. You can force-rotate videos of any length, and the app does not leave watermarks. It also works with videos in your Files app or those you download from Google Drive.

Lastly, because the videos get rotated at the frame level, the output is compatible with all video players on your Mac or Windows PC. Since these videos are saved to your Photos app, you can access them from iCloud.

Is Your iPhone's Accelerometer Broken?

If you've checked all the solutions above but still can't rotate your iPhone into landscape mode, it's possible your iPhone has a broken accelerometer. The accelerometer is what tells your device that it's been rotated and then rotates the screen to match.

The best way to check if your accelerometer is broken is to open an app that rotates like Notes and rotate it. If that doesn't switch to landscape mode as it should, and Rotation Lock is off, then you might have an accelerometer issue.

It's a possibility if you've eliminated every other probable cause. If you suspect this, you can make an Apple Store appointment at a Genius Bar to get it handled by experts. However, if you don't have an Apple Store nearby, you'll have to take your device to an Apple Authorized Service Provider.

If your iPhone is covered by Apple's one-year limited warranty or you pay for AppleCare , you can get its accelerometer repaired for free.

Is There Any Other Way to Rotate Your iPhone Screen?

Unfortunately, there is no other way to rotate your iPhone screen into landscape mode. This is Apple's choice, as it discontinued landscape mode on several devices.

Because of this, many apps won't support rotating screens either. While some do, if you're trying to rotate the screen in an app and it's not rotating, the app most likely doesn't support it.

While some potential fixes exist, like removing the Portrait Orientation Lock and using Assistive Touch, if you've tried all the methods here and your screen isn't rotating, a broken accelerometer might be the culprit.
