Landscape view

Welcome Urboiphoto,

Thanks for posting in the Apple Support Communities. I see from your post that your iPhone will not go into landscape view after updating to iOS 10. I know that landscape mode is very useful. I will be more than happy to help see what we can do to help.

Take a look at this article, it should help with your issue.

If the screen doesn't rotate on your iPhone, iPad, or iPod touch - Apple Support

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:

1. 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 .
   
2. If you have an iPhone 6 Plus or iPhone 6s Plus, turn off Display Zoom to rotate the Home screen.
3. 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:

1. Restart your iOS device.
2. If the screen still won't rotate, contact Apple Support.

The last thing mentions to contact Apple Support if you still can not rotate your screen.

Cheers!

Hi, do you still have this problem with your phone? I have the same problem with my iPhone 7 using iOS 10.2

I can't rotate the screen to landscape mode and the compass doesn't work at all.
