Does Dazz Cam work on iPhone Duo?
Mostly. Dazz Cam 2.17.7 is built with the iOS 27.0 SDK, so it fills most of iPhone Duo's inner display but leaves some space unused.

On the inner display
Built with the iOS 27 SDK, the app extends across most of the inner display, but some areas stay empty. It's usable, just not polished.
In Split View
iPhone Duo is the first iPhone that can show two apps side by side, and every app takes part — including Dazz Cam. Open it on the inner display, then add a second app next to it. You can save the pair and come back to it later.
Duo-specific features
None confirmed yet. Duo-specific features include side toolbars, layouts that react to the fold, and content on the outer display while the app is open inside.

Questions
Does Dazz Cam work on iPhone Duo?
Mostly. Dazz Cam 2.17.7 is built with the iOS 27.0 SDK, so it fills most of iPhone Duo's inner display but leaves some space unused.
Does Dazz Cam work on the outer display?
Yes. iPhone Duo's 5.4-inch outer display behaves like a regular iPhone screen, so every iPhone app works there as usual.
Can I use Dazz Cam in Split View on iPhone Duo?
Yes. On iPhone Duo every app can be placed side by side with another app on the inner display — developers don't need to opt in. How comfortable it feels at half width depends on the app's layout.
Why does Dazz Cam have black bars on iPhone Duo?
Apps built with the iOS 26 SDK or earlier run in a phone-sized window on the inner display, and iOS 27 builds can still leave some space empty. The bars disappear once the developer rebuilds the app with the iOS 27.1 SDK — you only need to update the app.
When will Dazz Cam fill iPhone Duo's inner display?
When its developer releases an update built with the iOS 27.1 SDK or later. We read the SDK of every new version of Dazz Cam within about a day of its release and update this page.
What can I do about the black bars until then?
Use Dazz Cam on the outer display, where it works like on any iPhone, or put it in Split View next to another app on the inner display so less of the screen goes unused.
