Call of Duty: Mobile for iPhone Duo

Call of Duty: Mobile has no announced version for iPhone Duo. As of October 6, 2026, the current App Store release is version 1.0.57, from September 7, and its release notes don’t mention the Duo. Activision has made no announcement that we have found.

Apple’s Human Interface Guidelines ask games on the Duo to change their aspect ratio rather than letterbox, and to fill the bands with artwork when they can’t. Activision hasn’t said what Call of Duty: Mobile will do. The only big games shown on the Duo so far are Zenless Zone Zero and UnGodly.

Call of Duty: Mobile will still open on iPhone Duo, like every app on the App Store. Closed, it looks as it does on any iPhone. Open, it won’t reach the edges of the inner display until Activision rebuilds it with Apple’s iOS 27.1 tools, which Apple only cleared for App Store submissions on October 5. The App Store lists an iPad version, so a layout for wider screens exists; nothing says the Duo will get it. More in how apps that aren’t updated run on iPhone Duo.
