Why Your iPhone Screen Won’t Rotate: Common Causes

Before diving into solutions, it’s important to understand why your iPhone not rotating screen occurs in the first place. The most frequent culprits include:

  1. Rotation Lock being enabled (the most common reason)

  2. App-specific restrictions (some apps don’t support landscape mode)

  3. Software glitches or bugs in iOS

  4. Hardware sensor issues (gyroscope or accelerometer problems)

  5. Accessibility settings interfering with rotation

  6. iOS update required for proper functionality

Understanding these root causes will help you better diagnose and solve your particular rotation issue.

Basic Fixes for iPhone Screen Rotation Problems

1. Check and Disable Rotation Lock

The first and most obvious solution when your iPhone screen won’t rotate is to check the Rotation Lock (also called Portrait Orientation Lock):

For iPhones with Face ID (iPhone X and newer):

  1. Swipe down from the top-right corner to open Control Center

  2. Look for the lock icon with a circular arrow (🔒↻)

  3. If highlighted, tap it to disable Rotation Lock

For iPhones with Home Button:

  1. Swipe up from the bottom to open Control Center

  2. Locate the same lock icon and tap to disable if active

Pro Tip: Some cases might make it difficult to access Control Center. Try removing your case temporarily if you’re having trouble.

2. Force Restart Your iPhone

If disabling Rotation Lock doesn’t solve your iPhone not rotating screen issue, try force restarting your device:

For iPhone 8 and newer:

  1. Quickly press and release Volume Up

  2. Quickly press and release Volume Down

  3. Press and hold the Side button until you see the Apple logo

For iPhone 7/7 Plus:

  1. Hold Volume Down + Power buttons simultaneously

  2. Release when Apple logo appears

For iPhone 6s and earlier:

  1. Hold Home + Power buttons together

  2. Release when Apple logo appears

This simple reset often clears temporary software glitches affecting screen rotation.
