The side switch on the iPad controls either rotate or mute, depending on how you configure the settings. Whichever one you don’t assign to the side switch appears in Control Center where you can turn it on and off.
Assigning Rotation and Mute in iPad Settings
If your iPad has a side switch, check to see where the iPad’s Lock Rotation setting has been assigned.
How to Toggle Screen Rotation On and Off in Control Center
You can access many iPad features and settings from the customizable Control Center, including the Lock Rotation feature.
The Problem May Be With an App
Not all iPad apps support orientation changes, so if the screen doesn’t rotate, click the iPad’s Home button to reach the main screen, and then try turning the device. If the screen rotates, you know it was the app, not the iPad, that prevented the rotation. There’s nothing you can do about this.
Still Having Problems With Your iPad Not Rotating?
Another reason your iPad won’t rotate is if it doesn’t know you’re trying to rotate it. This issue will happen if you aren’t holding the tablet upright. Rotating it on a flat surface isn’t enough to trigger it, so you might have to hold it up as if you’re taking a picture, and then rotate. If all else fails, reboot the iPad by turning it off and then back on. This simple approach fixes many problems.
