Check your settings and test with an app that rotates
Some apps don't rotate. Some might use only portrait or landscape mode, or switch depending on the content. To test screen rotation, open the Calculator app that comes with your device. If the screen doesn't rotate when you rotate the device, try these steps:
- If you see
in the status bar, Orientation Lock is on. To turn it off, swipe up from the bottom of the screen to open the Control Center, then tap 
.
- If you have an iPhone 6 Plus or iPhone 6s Plus, turn off Display Zoom to rotate the Home screen.
- If you have an iPad with a Side Switch, turn the Side Switch on or off.
