Hello Missesj,
Thanks for using Apple Support Communities.
I understand that you're expecting the "Now Playing" screen in the Music app to rotate in landscape orientation. Some apps, like the Music app, don't rotate. You can make sure the rotate function is working however by testing in another app, like Calculator:
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.
If you checked your settings and your screen still doesn't rotate when you use an app that should rotate (like the Calculator app), follow these steps:
- Restart your iOS device.
- If the screen still won't rotate, contact Apple Support.
If the screen doesn‘t rotate on your iPhone, iPad, or iPod touch
Take care.
