One popular iPhone feature is the ability to automatically rotate the iPhone's screen orientation depending on how the phone is held. This feature can become disabled, either intentionally or accidentally. When screen rotation is disabled, the iPhone's screen is locked in place and will not automatically rotate when the iPhone is held at different angles. iPhone users can fix this problem and reactivate screen rotation using the iPhone's main menu.
Press the "Home" button on the iPhone twice. This button is located just below the iPhone's screen. A menu bar will pop up on the bottom of the iPhone screen.
Swipe your finger to the right on the menu bar that popped up. This will display several new buttons.
Press the "Rotation" button, which is the grey button on the left side of the menu bar. This will immediately enable screen rotation, allowing your iPhone screen to rotate as you hold it at different angles.
