Questions
Does Bank of America Mobile Banking work on iPhone Duo?
Mostly. Bank of America Mobile Banking 26.10.06 is built with the iOS 27.0 SDK, so it fills most of iPhone Duo's inner display but leaves some space unused.
Does Bank of America Mobile Banking 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 Bank of America Mobile Banking 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 Bank of America Mobile Banking 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 Bank of America Mobile Banking 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 Bank of America Mobile Banking within about a day of its release and update this page.
What can I do about the black bars until then?
Use Bank of America Mobile Banking 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.
