Rotate your iPhone screen between portrait and landscape
Your iPhone can display content in portrait (tall) or landscape (wide) orientation. Most of the time, your phone automatically rotates when you turn it, but you can also lock the screen to one orientation or manually switch it. The method depends on whether you want to let your phone rotate freely, lock it in place, or force a rotation that isn't happening automatically.
The rotation controls live in your Control Center — the panel you pull down from the top-right corner of your screen (or up from the bottom on older models). From there, you can toggle rotation lock on and off, or you can go into Settings to change how rotation works across your entire phone.
Key Takeaways
- Open Control Center and tap the rotation lock icon to prevent your screen from rotating when you turn your phone.
- Most apps rotate automatically when you turn your iPhone sideways, but some apps like Messages and Mail do not rotate no matter what you do.
- If rotation is not working, check that rotation lock is off in Control Center and that the app itself supports landscape mode.
- Older iPhones use the mute switch on the side to control rotation lock instead of a Control Center icon.
Turn rotation lock on or off in Control Center
Control Center is the fastest way to toggle rotation lock. On iPhone X and newer, swipe down from the top-right corner of your screen. On iPhone 8 and earlier, swipe up from the bottom of the screen. You will see a grid of icons.
Look for the rotation lock icon — it looks like a phone with a curved arrow around it, sometimes with a lock symbol. If the icon is highlighted or colored, rotation lock is on, meaning your screen will not rotate. Tap it once to turn rotation lock off, and your screen will rotate when you turn your phone. Tap it again to turn rotation lock back on.
If you do not see the rotation lock icon in your Control Center, you may need to add it. Go to Settings > Control Center > Customize Controls, find "Rotation Lock" in the "More Controls" section, and tap the plus sign next to it.
Lock or unlock rotation in Settings
You can also control rotation through the Settings app, though Control Center is faster for day-to-day use. Open Settings and tap Display & Brightness. Look for an option called "Orientation Lock" or "App Rotation" — the exact name varies by iOS version.
If you see a toggle switch, turn it on to lock your screen in portrait mode, or turn it off to allow rotation. Some older iOS versions do not have this setting in Display & Brightness; if you cannot find it there, the rotation lock in Control Center is your only option.
Why some apps do not rotate no matter what you do
Some Apple apps are designed to work only in portrait mode, even when rotation lock is off. Messages, Mail, Notes, Reminders, and the Phone app will not rotate to landscape on most iPhones, by design. This is not a malfunction — Apple built them that way.
Third-party apps vary. Some support landscape mode and will rotate when you turn your phone (as long as rotation lock is off). Others do not support landscape at all. If an app is not rotating and you have rotation lock turned off, the app itself does not support that orientation.
What to do if your screen is not rotating
If your screen should be rotating but is not, start by checking Control Center. Swipe down (or up on older models) and look at the rotation lock icon. If it is highlighted or colored, tap it to turn rotation lock off. Your screen should then rotate when you turn your phone.
If rotation lock is already off and the screen still is not rotating, try closing and reopening the app. Some apps need to be restarted to respond to rotation changes. If that does not work, restart your iPhone: press and hold the power button and volume button together, then slide to power off. Wait a few seconds, then press the power button again to turn it back on.
If rotation still does not work after a restart, the app may straightforward not support landscape mode. Try opening a different app — Safari, Photos, or Maps — and turn your phone sideways to see if those rotate. If they do, the problem is with the specific app, not your phone.
Older iPhones: using the mute switch for rotation lock
On iPhone 6s and earlier, the physical mute switch on the left side of your phone controls rotation lock instead of muting sound. When the switch is in the down position (toward the back of the phone), rotation lock is on. When it is in the up position, rotation lock is off and your screen will rotate.
If you want to use the mute switch for muting instead of rotation lock, go to Settings > Sounds (or Sounds & Haptics) and toggle "Use Side Switch for Mute" on. This changes the switch back to controlling volume mute, and moves rotation lock to Control Center.
Frequently Asked Questions
Why does my screen rotate in some apps but not others?
Not all apps support landscape orientation. Apple's built-in apps like Messages and Mail only work in portrait mode. Third-party apps vary — some support landscape, others do not. If an app does not rotate even with rotation lock off, the app was designed that way.
Can I force an app to rotate if it does not support it?
No. If an app does not support landscape mode, there is no setting or workaround to force it. The app developer chose to lock it in portrait only. You can contact the app maker to request landscape support, but your phone cannot override their design choice.
What if rotation lock is off but my screen still will not rotate?
Close the app and open it again. If that does not work, restart your iPhone by holding the power and volume buttons, sliding to power off, waiting a few seconds, then turning it back on. If rotation works in other apps, the problem is with that specific app, not your phone.
Does turning off rotation lock use more battery?
No. Rotation lock being on or off does not meaningfully affect battery life. The rotation sensor runs either way — it is just a question of whether your phone acts on what it detects.
Can I rotate my screen in landscape mode and lock it there?
No. Your iPhone can only be locked in portrait mode. When you turn your phone to landscape, rotation lock automatically turns off so the screen can rotate. You cannot lock landscape orientation permanently.
