iPhone 8 Screen Orientation

Oh, I see. We can't diagnose that kind of issue remotely, sorry, but you could have your accelerometer checked at an Apple Store or Authorized Service Provider. After testing it, they'll give you the proper answer (along with all the available options):--> Apple – Location Selector

Thanks and regards

Well, if you rotate your device, it's normal.

You can avoid that behavior opening the Control Center and tapping the lock icon. The device will stay in portrait mode, until you tap again on that icon.

If you meant something different, please better explain your issue.

You are most welcome :-)
