How to adjust the horizontal screen and vertical screen of Apple mobile phone?

iPhone 13、iOS 15。

1, bring up the suspension window.

By default, Apple's mobile phone will automatically rotate its direction. Pull down the upper right corner of the screen to bring up the floating window of the mobile phone.

2. Open the lock icon

Locate the lock icon in the Control Center component and click it. The lock icon will turn red, and the vertical lock will be opened at the top, so the phone can't automatically rotate into a landscape screen.

3. Close the lock icon

When the lock icon turns white, the vertical lock will be closed. Holding the mobile phone vertically is the vertical screen. When the mobile phone is held horizontally, it will automatically become a horizontal screen.
