I can fix my iPad when the orientation is opposite and the screen won’t rotate when I rotate the device.
“I use my iPad as a tool.”
If your iPad screen is upside down and it won’t change when you try to turn your device the opposite way:
1. Go to settings
2. Go to general>accessibility
3. Turn assistive touch on
4. A black box with a white middle circle on the border now appears
5. Click on the box
6. Click device
7. Click rotate screen
8. Click the direction you want your iPad to face.
If it gets stuck again, just do this again.
