That's it. The Portrait Orientation lock is NOT on. While trying to watch a video I shot with the phone -- shot in landscape mode -- if I flip my phone to view in landscape, the video stays portrait (playing sideways).
iPhone 7 Plus, iOS 10.1.1
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 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.
Thanks. After a restart (which I should've done to start with), it is now working.
