The Screenshot specifications page lists iPhone Duo as an iPhone screenshot size:

Outer display: 1398 × 2034 and 2034 × 1398 Inner display: 2007 × 2853 and 2853 × 2007

https://developer.apple.com/help/app-store-connect/reference/app-information/screenshot-specifications

I cannot find a way to upload them.

In App Store Connect, the App Previews and Screenshots device selector on my app's version page does not list iPhone Duo. The only iPhone options are the existing display sizes.

In the App Store Connect API, ScreenshotDisplayType has no Duo case. The largest iPhone case is still APP_IPHONE_67. I checked the current reference:

https://developer.apple.com/documentation/appstoreconnectapi/screenshotdisplaytype

My questions:

Where in App Store Connect do I upload iPhone Duo screenshots? If the option is not open yet, is there a ScreenshotDisplayType case for Duo that I should use through the API instead?

Thanks.

Whoa! do you have iOS 27.1? Do you have a Duo? How are you taking screenshots?

Pretty sure this is going to be TBD from Apple. No one outside of Apple would know the answer to this at this stage. No one has access to Duo simulators yet, so any design work would be in third party tools like Figma etc.

So there's no way to actually get Duo screenshots yet.

I just provide 1398 × 2034 and 2853 × 2007, It`s ok?

Apple’s screenshot specs now list iPhone Duo sizes: 1398 × 2034 (outer portrait) and 2007 × 2853 (inner portrait), plus the landscape versions. The current App Store Connect API reference still does not list a Duo value for ScreenshotDisplayType, so I would not try to create a set with APP_IPHONE_67 and assume it means Duo.

If the web upload page still has no Duo option for your app, it may not have rolled out to that account yet. Check the screenshot specs page again and contact App Store Connect Support with a screenshot of the missing selector. The screenshots are optional until April 2027, even for apps built with the iOS 27.1 SDK.
