How to Lock Screen Rotation on iPhone Duo
About This QuickTip
Fed up with your screen flipping sideways at the wrong moment? On the iPhone Duo, the Orientation Lock in Control Centre works separately for the inner and outer screens, so each one can have its own setting. I'll show you how to keep the outer screen locked in portrait while the inner screen still rotates freely, plus one quirk to know about when your Duo is propped up in tent mode.

Having two screens on the iPhone Duo brings up some interesting things when you’re using the device. One of them is which way up the screen is actually going to be when you’re using it. Because, when you turn the phone, just like a normal iPhone or iPad, the screen will rotate as well. But then, when the phone is open, which way is the screen going to be facing? It’s all a little bit complicated.
Well, there’s a really handy feature built into iOS 27 on the iPhone Duo that means you can take control of your screen orientation at all times. Let me show you how it works. It’s super simple.

Okay, with my iPhone Duo closed, I’m currently in the Photos app. If I swipe down from the top of my screen, I can turn on Orientation Lock from Control Centre. It’s a little icon with a padlock and a circle going around it. We’ve had this before. And now, if I turn my phone sideways, the photo on the screen stays in portrait.
But when I open up my iPhone Duo, I do want it to turn. I want to be able to rotate it in any direction, even upside down, because I want that picture to look good however I’m holding it.
And the great thing is, Orientation Lock on the iPhone Duo is separate on the inner screen and the outer screen. So, if I go into Control Centre here with the phone open, you’re going to notice that the Orientation Lock is actually turned off. So, when the phone is closed, Orientation Lock is on. When the phone is open, it’s turned off.
And of course, you can turn it on here if you want to, but quite frankly, I’m not sure why anyone would. I think the joy of this is being able to turn it around and look at things in portrait and landscape. But the fact that these two settings are separate on the iPhone Duo is a really hidden little feature that can help make your device easier to use.
And so, if you enjoyed this QuickTip, I think you’re going to really enjoy this one next.
