Lock the screen rotation
Rotation lock keeps the screen at the orientation it is in, instead of following the device.
Do one of the following:
- Open the system menu and tap Turn on Rotation Lock or Turn off Rotation Lock.
- Open Display > under Screen, turn Rotation Lock on or off.
Hold the device the way you want it before you turn rotation lock on.
