Questions
Does 去哪儿旅行-订酒店机票火车票 work on iPhone Duo?
It works, but with black bars. 去哪儿旅行-订酒店机票火车票 5.3.30 is built with the iOS 26.2 SDK, so iPhone Duo runs it in a phone-sized window on the inner display.
Does 去哪儿旅行-订酒店机票火车票 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 去哪儿旅行-订酒店机票火车票 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 去哪儿旅行-订酒店机票火车票 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 去哪儿旅行-订酒店机票火车票 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 去哪儿旅行-订酒店机票火车票 within about a day of its release and update this page.
What can I do about the black bars until then?
Use 去哪儿旅行-订酒店机票火车票 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.
